Wood-pulp Revolution

The revolution from linen & rag to wood-pulp was caused by a chemical process (whose name I am forgetting). Without it, woodpuplp was un-economical base to make paper from (I'm told there was a way to make paper by stripping bark from young saplings... but that's not economical).

Disambiguation page?

I noticed this is a disambiguation page, but I can't see any good reason for that. Have I misunderstood the use of that tag, or should it be removed from this page? Whitepaw 21:28, 2005 May 1 (UTC)

There was this notice by the tag: "There should be a page disambiguating Paper (the matterial) and Paper (scientific publication)". Certainly; however, this page does not fulfill that function, and is therefore not a disambig page. I'd definately suggest that it be turned into one, though, and will try to do it when I get the time. - Haunti 10:40, 25 May 2005 (UTC)

Which type of

paper is used for making photos?

Pece Kocovski 11:03, 29 January 2006 (UTC)

photographic paper ?

Photographic paper is made from a rag paper which is free from ligin and ph netural, (Silversafe) most high grade paper is machine mould made (not continuios web) with raw cotton linters in high grade gelatine size.

Enjoying Paper?

"This man is enjoying the many benefits of paper in a safe, healthy way."

This line is completely irrelevant to the article, as is the picture. Wikipedia's job is not to show how paper is enjoyed, but what paper is and what its function is. I am going to remove it once more -- those who want to keep it, please state why here. I find the picture and caption irrelevant, almost hilariously so. Alexander VII 14:18, 2 February 2006 (UTC)

Something about thickness

What is paper ? A 3D object. We have length, width, weight ... we want more. They say in [1]

Bulk or Caliper : The thickness of a single sheet of paper, expressed in points. A point equals 1/1000 inch.

Blanks : Heavyweight boards ranging from 15 to 48 points in thickness, both coated and uncoated. Primarily used for package printing, point-of-purchase displays, poster cards, etc.

To evaluate, Google sez "(15/1 000) inch = 0.381 millimeters". But ... the article is made in such a way that I do not see where to add such info. Any ideas ? Thanks. --DLL 17:55, 17 May 2006 (UTC)

You can include it under "Preparation of the fibers", in 1.1. The section discusses both the preparation and the end result. If you want to talk about it, you can contact me at http://wiki.riteme.site/wiki/User:Dutchvanilla Dutchvanilla 23:36, 28 May 2006 (UTC)

Paper is discussed by the people who use it. A printer will talk about points, subdivisions of printing type. A merchant will talk about ream caliper, the space it will take up in storage. A trditional bookbinder will not mention the thickness, as good paper is a amorphous web of fibres which has internal air pockets, the colour of the paper is detirmined by these pockets. the binder will press the paper for 3 months in folded sections, prior to sweing, and 2 months after sewing to compress the text block, only then will he measure the paper thickness, before he sets the spine in glue - and covers it with a binding.

Contradiction

The caption under the image in "Four great inventions of ancient china" says that Cai Lun is the inventor of paper, while the article "paper" says that this is unlikely, as there is evidence that paper existed several hundered years before Cai Lun was born. In addition, the article "paper" states that the word paper comes from the ancient egyptian "papyrus," and the article "cyperus papyrus" says that this is probably a fok etemology. 208.58.170.134 14:55, 16 August 2006 (UTC)

Unfortunately contradiction is between articles is pretty common here. I've fixed the Four greatest article's caption to say "widely regarded". The root of the word I have no idea about. Megapixie 17:30, 16 August 2006 (UTC)

Paper may not have been invented by T'Cai Lun, he was the court official who told the emperor about its invention, and thus the man cited with its invention in History 105BCE. Our word for this material is actually tissue, or bark paper. Modern 'Paper' is more like the Arabic invention, inspired by Chinese paper, and comes from the fact that the Greek speaking scholars who first saw a sheet of paper mistook the product to be a new type of Papyrus, (which is in fact a laminate of reed stems, hammered together).

Standard Paper Sizes

I think it would be informative to have a section about the standard sizes that paper is available in and history about why different sizes are used for different purposes and in different areas (why do Americans use 8 1/2x 11 as standard paper size while Europeans use a different size? why is 'legal paper' longer?) —The preceding unsigned comment was added by 144.15.115.165 (talk • contribs) 17:17, 25 September 2006.

Ordinary Sheet of Paper

The most ordinary sheet of paper in the US in 2000 measures 8.5x11 inches, is sold in reams of 500 sheets, in cases of 10 reams, 20 lb weight, which equals 5 pounds per ream, 50 pounds for the case (net). Made from 100% clear-cut virgin Amazon rain forest, sold in office supply stores for about $25/case, so about half-cent per sheet.

Durability of different types of Paper

Maybe something should be said about the durability of different types of paper. The paper used in money, for example, is durable thru several machine washings, whereas regular paper is not. This is (I believe) due to the fact that it is made from linen and other long-fibre materials, versus the short fibre wood pulp. But I could be wrong.

It would also like to see something on durability, and the process breakdown of the fibers. E.g., would an expert contribute something about UV exposure turning cellulose to glucose? --Theodore Kloba 14:08, 4 August 2006 (UTC)

Paper, the type developed by Tai C' Lun was made from the bast fibers found in the bark of trees like the mulberry - exported to Japan, and still used in traditional paper, and from grass's. these fibers were not avliable in the far western provinces of China, the region where the army defeated in 751, at the battle of Talas was recruited. Thus the Arab army captured papermakers who had developed the traditional technique to be used with recycled materials, like clothes.

Papermaking started in Samarkand, and a shortage of water enabled the arabs to adapt the chinese method further, producing a thicker sheet of paper that was sun dried, and burnished with gum arabic to reduce its bulk. Unlike Chinese paper, and Papyrus, it could be written on both sides. The Technology was transfered to Baghdad, and Damascus, where it was sold to the Christians as Charta Damascura. The Early western europeans thought it was another form of Papyrus, and so called it Paper by mistake. The crusades distroyed the centre of production, and it was moved to Iran and Morish spain, where the first European papermill was constructed (Xiavia 1120). Rags, were used to make the fibres and bones the glue to seal them, as the europeans were not used to vegtable gums like the Arabs were.

First there ws a shortge of fresh glue (bones) so allum was added to the size to stop it rotting in warm weather. This introduced chemicals into the rag paper. Then the Dutch invented machines (Hollanders) to make the rag pulp in one day, as opposed to the 6 months required by the traditional rotting (retting) nd stamping method. The trditionl wooden stampers put in the odd oak fiber into the paper which would discoulour with time. Hollanders used iron combs, so rust spots appear around the 1750's. Also the rags were not heted up in a decomposition process, so specks of mould,(foxing) appear too. The rapid process also produces more damaged fibres, so the strnght of the paper is reduced marginally.

Then a shortage in rags led to specilist papers in the 18 century, Sailors uniforms were reduced down to blue sugar paper. ropes to brown wrapping paper. Soldiers uniforms to official recipts - hence English goverment recipts were pink, and French pale blue. Finally they looked at other fibres, and wood was discovered. Woodfibres however have a network polymer called lignin, which is reactive with UV light, and asorbs sulphur from the atmosphere. This turns the paper yellow when exposed to sunlight. Modern paper is treated by adding chalk to counter the acidic sulphur, and is bleached as well. But the chalk makes the fibers less durable. Chemicl (retting) process are used to prepare the fibres as well, which helps somewhat, but the pulp is still inferior to bank note paper, made from pure turkish linen.

Paper and cultural advancement

From the article:

Some historians speculate that paper was the key element in global cultural advancement. According to this theory, Chinese culture was less developed than the West's in ancient times because bamboo (although abundance of materials is generally the primary reason for the use of bamboo as opposed to scientific prowess) was a clumsier writing material than papyrus; Chinese culture advanced during the Han Dynasty and preceding centuries due to the invention of paper; and Europe advanced during the Renaissance due to the introduction of paper and the printing press.

Does anyone know where I could read more about this? — Preceding unsigned comment added by 220.238.98.112 (talk) 15:55, 11 July 2005 (UTC)

I m sorry, but archilogical evidence suggests that China was in fact more advnced in many areas. As were many of the Pagan cultures outside of Rome, which is the dominant culture in Western europe. So if great chunks of the globe were in fact more advanced than (Rome) Western Europe, it is history which is at fault, in that it is written by the victor, and Rome, as it continued by the Western Church, held back European development for over 500 years by some very niffty editing of the facts. Its the Arab development of Papermaking that saved this information for us Europeans to re-discover. Unlike Papyrus, early paper can be written on both sides and does not fall into little squares with age. Its not paper, but what you do with it.

Paper is a Chinese invention, however it can be argued that it held back thier development somewhat, because it is so smooth to write on, the Chinese system of writing was frozen in a very early form. Thus the Chinese with all thier technological advancements could not easily share and develop those ideas.

Writing is developed by the material that the information is written upon. Cuniform was triangular and angular because that is what is easier to read on wet clay. But cuniform is heavy and was restricted to the royal archives, so the Hittites and Messopotainas who used it never advanced above the competition.

Likewise, Egyptian was developed on soft sandstone and linen sheets, thus pictures were never shortened to make them easier to write. Egypt was fast in setting up taxes and a military system, but was held back because the new papyrus writing material was exclusivly retained for the rich to guide them through the afterlife, stored in scrolls too heavy for ordinary folks to hold. Egypt stood still whilst Greece, Carthage and Rome flourished. Religion was associated with the writing, thus it was not developed further.

Greek is written left to right because the first pens would blot on the papyrus if they were forced over the rough surface the opposite direction. But they had an additional problem, they had to carve into hard marble, so adapted thier aphabet into a much simplier form. The Greeks got Papyrus very late in thier history, thus has a simplified alphbet, and used it to spread thier knowlege in libraries and museums.

The Chinese developed from similar pictures to the Egyptians, but had been forced to make scratches on (Oracle) bone as they did not have a smooth surface. Of course, Chinese pictures were developed into characters, but an early development of silk then paper held back Chinese development in the modern age, as the charichters are harder to print. The writing system never developed. The royal and religious texts were formed, and science was stuck with a rigid writing form.

The development of the Arabic 22 letter alphabet developed out of a shortage of writing materials - is written right to left because they first wrote on linen sheets. Its the natrual way to write, as you can see the margin, and adjust your letters to look neater. However Fate held back the Great Arabic empires. Arabic vowels added as dots, proved so hard to add to typecast lead letters, that printing never took off despite the technology hitting Ciaro in 1300, because they had a good writing surface they had flourished, but an unfortunate link of thie alphbet to the holy texts meant that they were ultimatley held back in the industurial era.

The chinese invented printing 700 years before Gutenberg, however, because Gutenberg was using Roman (Latin) letters, developed from Greek - for carving onto hard marble surfaces, he had only to mke 26 letters for his moveabal type. The Chinese still use 900 symbols. China is only just entering the industurial age with the development of the computer, like the Middle East.

In the West however, the roman text was not linked to religion, it was a pagan invention, and thus it was not sacred and could be adapted, changed and modified. Paper was a cheap material that allowed printing to spread knowlege and that is what caused global advancement.

Papermaking

The article on papermaking is only on the history of papermaking and gives a very brief description about how to make a sheet of paper by hand. There is no point directing anyone to that article for a description of the modern papermaking process. This article does a much better job, although it does need some additional information, for example about beating the pulp to free the fibers before laying down the sheet. Beating is acknowledged as the most important step in papermaking, yet is not even mentioned in the article.Silverchemist 04:35, 2 October 2007 (UTC)

Paper Weight

The weight of paper, 20lbs, 24lbs, 68lbs, etc could be discussed. Or is that in another article? 20-24lbs is generally printing paper, 68lbs is cover stock, and 110+lbs is card stock. The story of that weight is- when paper is produced, it is all made into a standard size sheet, no matter what the thickness, and then cut. A full uncut sheet (I'm not sure of the size) will weigh 24lbs, 68lbs, etc.

At least, this is what a sales person from Hammermill told me when Hammermill switched machines and tried to change the weights of their papers, creating mass confusion. Can any one refute or confirm this? I think it would be cool to have in the article, but I don't have any sources.

Paper Weight Demystified

Paper weight is an easy to understand formula when using metric measure. In metric measure all paper weight is based on how many grams per square meter per single sheet of paper or G/M2. So you might see a weight the likes of 100 G/M2 or 90 G/M2. All paper grades are measured in this same manner in metric paper measure.

On the other hand paper weight in imperial measure which is used primarily in North America is slightly confusing. All imperial paper weights are measured depending on the most popular end use of a particular grade. So you might have a text paper, cover paper, bond paper or writing paper to name a few of the more common paper basis weight categories. Each of these paper grades has its own “basis size” and then is measured by weighing 500 sheets of each basis size. As an example a text paper is based on the basis size 25 x 38 x 500 sheets = X lbs. and is referred to as an X lb. text paper.

Here’s the confusing part. You can have two sheets of the same paper and weigh each of the sheets based on different basis sizes and you will have two different paper weights for the same sheet of paper. Because of this peculiar situation you must always know which basis size is being referenced. When a paper is referred to as an 80 lb. without the basis qualifier, text, cover, etc. you cannot be sure what weight of paper is being referenced. It could be a text basis or a cover basis or any basis of the many basis sizes commonly used in North American paper measure. Therefore, to be clear and accurate when you are describing a paper’s weight you must always identify the paper you are describing by calling it X lb. text, X lb. cover, X lb bond, X lb. writing or the same with any of the other basis size categories when X indicates the paper’s weight.

Good Lord, what a mess. Yet another reason we should all switch over to the metric system. [sigh] —The preceding unsigned comment was added by 24.6.66.193 (talk • contribs) 21:30, January 17, 2007 (UTC)
Metric conversion, yes, but it won't help, here. This issue arises because manufacturers apply a weight to paper when it's in any number of basic forms which end customers do not see and are unaware of. There's no explanation how what they are seeing has been cut down -- or from what basic size it's been cut down. What would help is if manufacturers adopted something more intuitive -- such as the weight of 1 square inch of 500 sheets. Alpha Ralpha Boulevard 10:28, 11 November 2007 (UTC)

I think you problem is that you are trying to describe paper in terms of North America, the last place on earth where it was historically manufactured in the traditional manner.

Paper was made in a mould, the paper was formed on a wire support, which would show up in the finished sheet as a (watermark) light pattern. the thickness of the paper was detirmed by the depth of the frame which was used to hold the paper pulp over the support, whilst the water was pulled through by suction. The dimensions of the frame were historically give names, and the papermakers mate, the coucher (layer) would lay these in a pile of 480 (English) or 500 (French) sheets with felt seperators in between. This pile was then pressed to remove the excess water, and hung over raop for 6 months to dry. that pile was called a ream, and paper was sold by the ream, expressed by its weight.

Paper was made locally to where it was used, so standard sized sheets (with local variation) were made for particular jobs. The royal, used by government in England used to have the royal crown and arms on it, until Oliver Cromwell decided to remove them in the English Cival War (1640). When asked what to replace them with, he suggested a clowns hat, and thus a Fools cap (foolscap) watermark and paper size was established. As printing improved, so the demand for larger sheets of paper was created. Imperial was superceeded by Elephant, and Double imperial, until the invention of the papermaking machine created a continous roll of paper.

Modern paper is sold by a German system, where two sheets of A4 paper plced side by side will equal one sheet of A3. the weight is expressed as its Gramms per Square Meter, but there was an Imperil system in oz per square Inch. However it arrived too late, and the German system of A sizes was more easier to understand.

Moved

Moved this paragraph to the papyrus & parchment section: "In America, archaeological evidence indicates that a similar parchment material was invented by the Mayans no later than the 5th century AD.[1] Called amatl, it was in widespread use among Mesoamerican cultures until the Spanish conquest." Added this summary sentence: 'The parchment is created by boiling and pounding the inner bark of trees, until the material becomes suitable for art and writing.' Reasons being the Mayan parchment resembled papyrus of the ancient Egyptians, and wouldn't be 'paper' as in being made of the finely ground pulp and plant fibers.

Re: Opaqueness of Paper?

Very heavy book paper (like what's used in textbooks) generally has a mineral coating on each side applied after the paper was originally dried.Exactly what that coating is made of is usually a closely-guarded trade secret, but basic constituents are usually some kind of clay or opaque mineral or mixture thereof (kaolin or ground calcium carbonate are often used and sometimes titanium dioxide and most recently hollow latex particles), a plasticizer (often latex) and rheology adjustment chemicals (so that the coating can be run at high speed on the machinery). The make-up is adjusted depending on what pronate and chemicals such as fluorescent whitening agents are also added to improve the optical properties before the coating.

Coating weights can often make up a substantial amount of the paper weight.

Potassium sulfide is water soluble and generally wouldn't stay with paper as it was formed. So no matter the optical properties, probably wouldn't make an economically feasible opacifier.

Mulberry Paper

Paper made from mulberry trees was created in Korea, not in Japan. — Preceding unsigned comment added by 68.36.193.198 (talk) 19:06, 15 April 2007 (UTC)

Wrong, Bhuddish monks from India took the idea of the leaf book and Bhuddism into China in Muthabah script on Palm leaves. Then they trained Chinese monks to spread the stutra, and some took Bhuddish ideas on Chinese mulberry paper written in Chinese charachters into Korea. The chinese liked the indian leaf books, so they copied them in paper and silk, creating the concentina book.

These trained Korean Monks, who took the Indian ideas about Bhuddism on Chinese paper, in Korean variations of the chinese concentina books written in Chinese charachters into Japan. The Japanes thanked the Monks by Inventing Printing, and sending back that idea via Korea to China. The Koreans also invented movable type, but the new alphabaet of 98 charachters proved two expensive to manufacture, so It never took off. — Preceding unsigned comment added by 86.131.77.26 (talk) 15:03, 5 July 2007 (UTC)

Disagree According to Joseph Needham "Science & Civilization in China" it was China who came up with printing first. But do the impractically of movible type for the Chinese character system it was discontinue and single wood block printing which can be easily carved for characters was used more readily.

The concept of books in China came from slivers of bamboo tied together to form a page.

History Islamic paper

I believe someone needs to mention the change of Chinese paper by the Islamics (civilization) from the brush form to the pen form. Faro0485 (talk) 17:01, 27 May 2009 (UTC)

Usage of the Term "Arabs" is incorrect

{{editsemiprotected}} In the first line of the 11th paragraph ("where the Arabs invented a method to make..."), usage of the term "Arabs" is incorrect as not all the people living in the Islamic Empire were Arabs. There were Persians and Turks and many other ethnic groups as well. Use the term "Muslims" instead. Amirms (talk) 18:38, 5 January 2009 (UTC)

Not done: Given that Baghdad was the capital of the Arab Empire at the time, the term "Arabs" seems appropriate in this context. haz (talk) 09:13, 7 January 2009 (UTC)
A better term would be Islamic. The term islamic is used. We recall that the civilization was not Arab, it was Islamic (post islam, not post arabs - which arabs are as ancient as ancient). Faro0485 (talk) 17:03, 27 May 2009 (UTC)

The introduction of paper into Europe, from muslims through Catalonia

Tradition wants that Arabians began to manufact paper after having made some Chinese papermakers prisoner in the Battle of Talas (original reference), near Samarkand, in AD 751. Reference: History Today Mag, Jun 2009 par7133 01:30, 11 June 2009 (UTC)

Antioch was a traditional papermaking coast town, but after the Crusader seige of 1096, production moved to Damascus and up to the 9th crusade of 1272 it was used to ship the Charta Damascura to Europe.

Paper remained known like that for many years before to enter in Muslim Spain via Marocco. Reference: History Today Mag, Jun 2009 par7133 01:30, 11 June 2009 (UTC)

The first european paper mill was started in Xativa (Valencia) in year 1150 by Arabians.

but there is archaeological evidence for paper in use in the same location from 1056. Reference: History Today Mag, Jun 2009 par7133 01:35, 11 June 2009 (UTC)

Christians conquered Valencia in 1238 and maintained this fertile industry. King Jaume I was the first king in Europe to use paper for official documents. Paper was not readily accepted everywhere and Catalonia kept a leading position in the making of paper for three centuries more.

Renaissance artists and lawyers contributed to the rise of paper. At first, Italian lawyers began to use paper to record deeds, later written records of contracts and other legal transactions became more popular. Reference: History Today Mag, Jun 2009 par7133 01:35, 11 June 2009 (UTC)

In 1260, Mamluk sultanate shifted the Empires capital to Cairo and violent crusade attacks happened causing the arabian production start to decrease.

By 1284 european paper trade was very important; there were only two producers: Catalonia and Lombardia (Italy);

Italian paper manufacturing centers of Amalfi and Fabriano (Italy) flourished competing with Catalonia.
In the beginning of the 15th century latter developments and the defeat of Damacus under Timor and his Mongol hoard (original reference) constrained Arabs to abandon their production and import cross signed paper from Europe, causing religious concerns and the emission of a fatwa. Reference: History Today Mag, Jun 2009 par7133 01:45, 11 June 2009 (UTC)
Developed in Germany the printing press arrived to England by William Caxton in 1476. Mainland businesses started to flourish by the publication of texts in english, religious texts, very lucrative activity, official documents, but literature too, and particularly concentrated in London, Oxford and Cambridge. Other texts like the scholar books, in Latin, continued to be imported. Reference: V&A, Jun 2009 par7133 11:30, 16 June 2009 (UTC)

For many years Church remained the only literate community and thus the main parchment customer. When printing press was reinvented by Gutenberg, paper appeared superior to parchment and wide spread for ecclesiastic uses too (original reference).

In Catalonia it was called "paper" and in Italy it was called "carta". Paper was made by the first time in France in 1318 where it was named "papier catalan". Paper production in Holland began in year 1340 in a mill founded by catalan craftsmen.

The catalan name "paper" was exported to many european languages. German: papier, English: paper, Polish: papier, Check: papir, Croacian: papir. Other languages (Russian: bumaga) took the root from the Greek word for "cotton".

The word paper comes in turn from papyrus, an egiptian plant used to make a different kind of material. Arabians learned the art of making paper after the conquest of Samarcanda, in year 751. **And the last sentence must be referring to the Battle of Talas, I guess (moved above par7133 11:30, 16 June 2009 (UTC)).

'Paper' is a Greek word, 'Charta' the Latin word, the two languages of the Reformation. The Byzantium church had continued to use parchment, invented in Permagum. where the Russian Orthadox word for paper comes from.

By 1284, most of the paper in Europe, still a new material - was being imported from the Middle East. Antioch was a traditional papermaking town on the coast, but after the Crusader seige of 1096, production was moved to Damascus, however, up to the 9th crusade of 1272 it was used to ship the Charta Damascura to Europe. The production was decreasing, as the Mamluk sultanate had shifted the Empires capital to Ciaro 1260 because of the crusade attacks. (moved above par7133 11:30, 16 June 2009 (UTC))

In 1272 the flow stopped, and Fabriano in Italy became the new source of this material. Charta Papyir stopped being produced after Timor and his Mongol hoard sacked Damacus in 1400. Paper was a cheap alternative to parchment, because the church was the only literate society, and thus its only customer. When printing was re-inveted by Gutenberg, paper had a use, where it was superior to parchment, and thus papermaking spread. The words used reflecting the European language of the reformation - Greek and Latin (moved above par7133 11:30, 16 June 2009 (UTC)). Dave Calladine

Production figures

Aging

Paper, i guess especially acid paper, darkens with age. Deserves some discussion, perhaps along with the slow fire coverage in Paper#Nineteenth Century advances in papermaking.
--Jerzy•t 03:35, 21 September 2007 (UTC)

Paper made with mechanical pulp, which retains most of the original lignin from wood, will yellow and degrade with age. Newsprint is a common use for mechanical pulp. Bleached chemical pulp, like fully bleached kraft pulp, makes paper which is light stable and not prone to degradation with age. "Slow fire" resulted from the use of alum (aluminum sulfate) in papermaking. Alum makes the paper acidic (pH approx 4.5), allowing acid hydrolysis of the glycosidic bonds which join glucose units together to make cellulose. I will see what I can do to address these issues in this and related articles. Silverchemist 20:24, 27 September 2007 (UTC)

Also,the process of "Yellowing" should be included:

The lignin in the cellulose of paper, will eventually turn paper yellow in the process of oxidation when exposed to sunlight and air. However, in making fine whhite paper, the lignin is separated and discarded by use of a chemical solvent. [1] —Preceding unsigned comment added by 220.244.130.72 (talk) 00:22, 8 November 2009 (UTC)

Wood-Based Paper vs Wood-Free Paper

Typo in main text - [Secion on Chemical Pulping 3rd Paragraph] alluded to Wood-Free paper being the same as Non-Wood Papers. Minor Edit Richard416282 (talk) 05:55, 12 February 2010 (UTC)

Edit request from 69.200.224.93, 12 June 2010

{{editsemiprotected}} Add the following key, conversion table and formula to the "Types, Thickness and Weight" section and tag as "North American paper measurements":

Key: "#", "lb", and "pounds" are used interchangeably to refer to standard paper weights for different types of paper. (Citation: http://www.theofficeguide.com/copy-paper/ See: "Copy Paper" - "Paper weight is specified by basis weight in pounds (# or lb.)")

One way to describe paper is in terms of having a certain standard weight (regardless of the actual quantity, size, or physical composition of the given paper). Examples of paper description in terms of standard paper weight: "an 8.5" x 11" sheet of 20 lb copy paper;" "a case of 32# bond paper;" "10 packs of 8" x 5" 24 pound paper," etc.


Formula: Mass of nonstandard paper = mass of a standard paper ream X “area ratio” X “weight ratio.”

"Area Ratio" = area of sheet in question / area of standard sheet (93.5 square inches)

"Weight Ratio" = standard weight # of typical sheet / 20# sheet

Mass of a standard (8.5" x 11", 20#) paper ream = 5 lbs. .

Size Sheet Area in inches Area Ratio Weight Ratio (15#/20#) Lbs/Ream
Letter 8.5 x 11 1 .75 3.75

Paper History Review

This article on paper is pretty good. It gives an accurate definition of what paper is, what it's made of, and it's history. It also tell how it's made, how it can be recycled, what are the different ways in which paper is used, the types of paper, and possibly the future of paper. There are some missing sources for some of the sections in the article such as in the history section and the types, thickness and weight. the illustrations are useful because they help to show they different types of paper there are, the tools used with paper, and what paper materials look like up close. It does cover the subject quite throughly except for the history section is a little off with it's information on what was used to make paper in China, and it also doesn't talk about what types of materials were first used for paper in the Middle Ages that was difference from the paper used in China.

I can't believe that an article of this length and depth on such a fundamental product as paper has absolutely no mention of the massive environmental impact of modern paper production or direct and obvious links to such information. There is a link to the Papermaking article, which again does not mention environmental issues directly, although this in turn links to the Pulp and Paper Industry article which does, although the piece is very short and rather inadequate. When I get around to it I will fix this problem if no-one else does. Spiridens (talk) 08:45, 19 February 2012 (UTC)

Is Papyrus & Mayan parchment considered paper?

The Egyptian papyrus and the Mayan parchments are both created from pounding reeds and/or tree park. Paper however, is made from shredding and pressing together cellulose fibers, rags, or pulp. Therefore I don't think that would meet the definition of "paper"? Intranetusa (talk) 00:57, 6 April 2008 (UTC)

You are right. these are not paper. --Wayiran (talk) 21:00, 23 June 2008 (UTC)

Reeds and bark contain cellulose, as does virtually all plant matter. Ancient historical 'paper': Egyptians used reeds, Mayans used bark, Chinese used rags or plant inner bark (bast fibres) e.g. mulberry & bamboo.
Modern paper uses none of these things - it uses wood, and it began in the 1800s in Europe (see Fourdrinier machine)
I am yet to see a reliably sourced definition of paper that would include Chinese 'paper' but exclude papyrus (or Mayan paper). The ancient Chinese may be able to be credited with the incremental step of moving from the Egyptian shredding+pressing to pulping+pressing, but that's it.Utopial (talk) 10:28, 3 September 2009 (UTC)

As Utopia1 said, there are many kinds of paper. Papyrus paper as developed by the ancient Egyptians was definitely paper under any definition that would include early chinese paper. Nowadays we have common, low quality paper from wood, higher quality stuff from rags, one of the highest quality papers is made from hemp, and is, I believe, what paper money is traditionally made from.

Brightness

Office paper is rated for brightness; is there a place to work that into the article?

Paper brightness (albedo) is relevant to more than just office paper. It comes up in printing, photography, and color-grading diamonds, just to name a few. The albedo of white paper is usually on the label as well as the advertizement, e.g., when purchasing paper online. In North America brightness is usually given in TAPPI numbers, also known as GE or TAPPI/GE. Two other systems are ISO and D65. [more info on TAPPI, ISO, and D65] Office paper sold in the US will typically have a label that looks something like this: "Premium Laser Paper, 98 GE/114 ISO, 24 lb, 500/SH, White" ISO numbers tend to be higher because they have a different way of measuring albedo. The GE systems filters out ultraviolet while ISO doesn't. With fluorescence you can have an albedo greater than 100%.
A related concept, whiteness, has to due with color saturation, or lack thereof.
Color-grading diamonds is done on special trays made of white bright paper (or card-stock) folded into a v-shape at the bottom so that the stone's table (face) rests on white paper and so that, when viewed from the side, white paper is in the background. The difference between one color-grade and the next is so slight that most people can't see the difference even under ideal laboratory conditions. Zyxwv99 (talk) 22:47, 1 May 2013 (UTC)

POV in the "Conservation" section.

The whole section sounds very POV and unsourced, especially Several major Asian producers, for example, with strong connections to their respective Governments and bureaucracy have been systematically stripping rainforest for many years. Often the logs are transhipped to other countries to disguise the damaging trade and These concerns are not merely side issues but rather display the comprehensive problems that occur when production dominates thinking. As in many problems over the years the mistaken belief is, and has traditionally been, that nature can cope. The short answer now is that nature cannot and increasingly the state of the ecosystems has been rendered such that the position has, and is becoming, terminal. Joyous 00:57, Mar 22, 2005 (UTC)

Paper is made from soft woods, not hardwoods. The fibres in rainforest trees are short and fat, and have vast amounts of network polymers (ligin) surrounding them. Thus they are unsuitable for making paper. Other plants in the region, Manilla sisal is much better.

Soft wood fibers are much longer, and more suitable for paper production, and the paper industury plants about three times more trees than it cuts down, as an insurance policy against forest fire or diesese preventing its future production. It has to think about 20 years ahead, and is one of the most environmental of industuries. The logs are floated down the rivers, to the mills, the bark is turned into compost for the saplings of future planting, and also sold to garden centres. the finish product is then shipped by rail or sea.

Recycled paper is however the bug threat. it takes three times the energy and some nasty chemicals to remove the ink and other media from a piece of paper, than it does to produce a new sheet. The recycled paper is so weak, that it not durable for any length of time, so is only fit for nsty toilet paper of middles of cardboard box industury, and the carbon foootprint in recycling this productas paper is enourmous. It would be better to burn the old paper.

Dave Calladine, Paper Conservator

...Dave that sounds a bit dodgy to me - I was always under the impression that paper was an environmentally destructive product (chemicals to produce/whiten etc), and I doubt that recycling paper uses three times the energy than virgin pulp to produce... actually IMO none of the paper pages on wikipedia really explain how damaging paper is to the environment.

... dave, your perspective also sounds like another extreme POV, when you talk about recycled paper being so weak. But, your perspective might be right, so is there some way you can better explain the math behind the assertation that paper isn't damaging? There is a simple observation I will make. All paper requires land and machinery. Land that is used for paper - as in - replanted forests are not nearly like the original virgin rainforests or forests or grasslands. To turn grassland into forest removes the habitat for the grassland animals as well. In all cases, paper requires trees, paper produced from planted forests means land being used inappropriately rather than being allowed to grow entirely naturally. A better perspective might be that: "There are complex issues to do with mathematics between the people who believe recycling is unwise due to the energy cost and carbon produced, and the people who would prefer more recycling than destruction of forests and grasslands and natural habitats for created single-species forests with potentially limited and far simpler ecosystems." Does anyone with a sharp pencil and a calculator, a few factual tables, math skills and a bit of time care to insert some facts on the view of paper demand leading to deforestation and replanting being better than recycling and leaving original forests alone, or leaving regrowth to naturally recover rather than constant harvesting?

First paper (Papyrus) was manufactured in Egypt and Southern Sudan as far back as the fourth millennium BCE. The earliest archaeological evidence of papyrus was excavated in 2012-2013 at Wadi al-Jarf, an ancient Egyptian harbor located on the Red Sea coast. These documents date from ca. 2560-2550 BCE (end of the reign of Khufu). This was over 4000 years before it was developed in China during the early 2nd century AD, possibly as early as the year 105 A.D., by the Han court eunuch Cai Lun. 174.93.45.57 (talk) 23:18, 12 August 2013 (UTC)

Ambiguity in "Future of paper"

I suggest a slight change to the wording in "Future of paper". (I'd do it myself, but the page is protected). It currently reads:

Some manufacturers have started using a new, significantly more environmentally friendly alternative to expanded plastic packaging made out of paper, known commercially as paperfoam. The packaging has very similar mechanical properties to some expanded plastic packaging, but is biodegradable and can also be recycled with ordinary paper.

I'd propose it changes to something like:

Some manufacturers have started using a new, significantly more environmentally friendly alternative to expanded plastic packaging. Made out of paper, and known commercially as paperfoam, the new packaging has very similar mechanical properties to some expanded plastic packaging, but is biodegradable and can also be recycled with ordinary paper.

It's fixing the potential ambiguity in the phrase "...a new...alternative to expanded plastic packaging made out of paper..." On first reading that I was confused, thinking "What exactly is an 'expanded plastic packaging made out of paper'??" A few re-reads made it clear that the word "alternative" was meant to refer only to "expanded plastic packaging" and not to "expanded plastic packaging made out of paper", but the phrasing can catch out the unwary. (This is a lot of words for a simple change; as I said, I'd have done this were the page not so heavily protected.) Sleety Dribble (talk) 01:45, 26 July 2015 (UTC)

I made the change. Before your explanation, I thought the objection was to "paper, known commercially as paperfoam". That really was some messed up text. Willondon (talk) 06:48, 26 July 2015 (UTC)

Edit request on 28 January 2015

Please correct the caption of the picture with the kitchen roll. It should read "Different types of paper" instead of "Different typologies of paper". "Typology" is not a fancy word for "type". It means something entirely different. See, e.g., http://dictionary.cambridge.org/dictionary/british/typology

I second and reactivate this request. At most, a typology could be regarded as a set of types, although more commonly it is the study of types. But typology it is not itself a type. See, for example, Alberto Marradi, "Classification, Typology, Taxonomy" in Quality and Quantity: The International Journal of Methodology, XXIV, 2 (May 1990): 129-157 Sleety Dribble (talk) 02:09, 26 July 2015 (UTC)

This is my first time editing on Wikipedia.  I used MS Word to draft these suggested edits.  Then I did a copy-and-paste.  My Word document had suggested deletions in 'lined-through', suggested edits in green; my reasoning was presented in [highlighted green surrounded by square-brackets].  Unfortunately, those word-processing niceties, which would have made this edit a breeze to understand, were stripped between the copy and the paste.

Since I am experienced with Wiki editing (hundreds of hours using a subset of Wiki mark-up), I would prefer that someone allow me to edit the page (or a facsimile of the page), then review it for inclusion or discard. I labored 4.5 hours on crafting the words -- that's my style when writing for publication -- but now, as I read what's below, I find a jumbled mess. I tried doing "remove this" and "use this", but... Sorry. I offer it "as is", and without the citations.

remove this [Applications] Use this: [Use in Many/Most Human Endeavors] remove this [Paper can be produced with a wide variety of properties, depending on its intended use.] Use this: Paper is used in many different ways. • For representing value: paper money, bank note, cheque, security (see security paper), voucher and ticket • For storing and sharing information: book, notebook, magazine, zine, newspaper, art, zine, newsletter, letter [magazine is immediately followed by zine so that reader is aware that these are two distinct examples] [As a portrait artist, I'm offput by categorizing 'art' as simply storage of information; it should have its own bullet!] • For art: painting (as a surface upon which paint is deposited), sketching, collage, sculpture, cartoon, photography, papier-mâché, origami, paper planes, quilling, color display (paint chips and color wheels), • For personal use: diary, note to remind oneself or to someone else etc.; for temporary personal use: scratch paper, blotting paper • For communication: between individuals and/or groups of people. • For communication between individuals and/or groups of people: signs, billboards, posters, maps • For packaging: corrugated box, paper bag, envelope, Packing & Wrapping Paper, Paper string, Charta emporetica and wallpaper, excelsior [inappropriate capitalization] • For cleaning: toilet paper, handkerchiefs, paper towels, facial tissue and cat litter paper napkins, disposible mop-head (e.g., Swiffer) • For pet care: cat litter [cat litter is paper??], pet-diapers, bird toys, animal training, nesting material • For healthcare and personal care: toilet paper, facial tissue, sanitary napkins and tampons, adhesive tape and bandages, wound dressings, disposible gowns • For construction the built environment: emery paper, sandpaperpaper honeycomb, used as a core material in composite materials, paper engineering, construction paper and paper clothing [construction paper' has nothing to do with construction!], blueprints, electrical insulation paper (see also dielectric and permittivity), maquettes, Tyvek House-Wrap • For clothing: hats, diapers, fashion design, disposible underwear, "runway tape", buttons, jewelry, wigs • For science and industry: litmus paper, universal indicator paper, paper chromatography, filter paper • For sports and recreation: playing cards, scorekeeping, board games • For other uses: emery paper, sandpaper, blotting paper, litmus paper, universal indicator paper, paper chromatography, electrical insulation paper (see also dielectric and permittivity) and filter paper

Paper is described in terms of its characteristics, including thickness, weight, porosity, color, texture, durability, acid-content, method of production, coating, source of its raw material, etc. The intended use of the paper determines the characteristics it must have and how it is to be manufactured. An instance of this contrast is charta emporetica (which is manufactured to be porous) and Tyvek (which is manufactured to be waterproof) [needs citation]. Another example: paper towels (which are easily compacted) and playing cards (which bend, but resist folding).

[I'd like to see the above bullets reworked as separate subheadings to "Categories of Use". If so, the following line would belong in the "For Storing and Sharing Information" subsection.] It is estimated that paper-based storage solutions captured 0.33% of the total in 1986 and only 0.007% in 2007....

china was first

"Papyrus and parchment" should be replaced in history part. Chinese were first who invented paper. First of all this part doesnt have reliable source, besides the dates which is mentioned for that is 5th century AD which is 1500 years after chinese. check britannica, encarta or any other reliable source, Chinese were first who invented paper, and putting papyrus at the top of history part is meaningless. --Wayiran (talk) 20:59, 23 June 2008 (UTC)

Provide a reliably sourced definition of paper that includes chinese paper and excludes the others. As i posted above, Chinese/Egyptian/Mayan etc 'paper' all used rags, leather & non-wood (plant cellulose) materials. Modern paper uses wood. Either all or none of the Egyptian/Mayan/Chinese/etc materials are paper. One thing is for sure - the benchmark is modern wood based paper. —Preceding unsigned comment added by Utopial (talk • contribs) 10:34, 3 September 2009 (UTC)

It is disappointing that the Ancient Egyptians' papyrus paper has been deleted from the article. The Egyptians were using paper more than 2,000 years before China improved the technology. To maintain that paper is a Chinese invention is to attempt to rewrite history. Of course if the Chinese really did invent paper then we at least have to credit the Egyptians with developing time travel, which would let them get the technology from the future. :) Miriam e (talk) 15:34, 23 July 2012 (UTC)

The Wikipedia article on papyrus gives a couple of sources to early use of papyrus. "Papyrus was first manufactured in Egypt as far back as the third millennium BC." reference: H. Idris Bell and T.C. Skeat, 1935. "Papyrus and its uses" (British Museum pamphlet). Miriam e (talk) 15:55, 23 July 2012 (UTC)

Then please remove Gutenberg "inventing" the printing press. You are just a bunch of sinophobes trying to discredit everything the Chinese has contributed. --178.7.41.47 (talk) 20:22, 26 August 2017 (UTC)

Cotton vs. Wood

The article currently states

"cotton based tissue papers are ... far more environmentally friendly than wood papers, as they are made from renewable materials."

This seems wrong to me. Cotton and wood are both renewable materials, right?

Technically yes, but in practice it's probably much more difficult to replenish forests at the same rate as you consume them than it is to replenish cotton fields - in logging the entire tree is destroyed and must start again from scratch, and it takes years to regrow a tree to the same size as the ones that are felled; I think cotton can be harvested without destroying the plant at all (I could be wrong - the wikipedia page on cotton doesn't mention it), but even so, it'll probably grow back much faster than a tree will.
Just because an entire tree must be harvested does not mean that it is not environmentally friendly, and I don't think a regrowth rate is a strong enough argument to justify calling foresting environmentally unfriendly. At least, "far more" is too strong, and at most, the whole statement should be stripped of its POV. Akrabbim 22:29, 21 February 2006 (UTC)
In cutting down the entire tree you also have an entire tree to make paper out of. A tree can weigh hundereds of tonnes and most of that can be turned into paper. With cotton the time from seed to harvest is far lower but the yield is also far lower. The growth rate should therefore be meassured in kg of finished paper per ha of land used and year. Cotton also has other disadvantages when compared with trees; it has to be grown in tropical areas where the land could have otherwise been used for growing foods and is thus in higher demand. Trees can be grown in far more varied climates, further north than the polar circle. Colder areas are generally less inhabited and less utilised, they also contain far less species diversity that may be threatened by agriculture. Forests, even artificial ones, may house wildlife that cotton plantations cannot. Trees are more robust and require less maintenance than cotton, which may have to be treated with pesticides and herbicides which can dammage the surrounding environment.--88.131.71.181 (talk) 10:53, 11 November 2019 (UTC)

Cotton based tissue papers are thin and will break apat with use! Cotton made paper - if hand made will last for over 400 years, and is very strong. however, it depends on the source of the cotton, a very water dependant crop. most of Uzbekistan and Turkmenistan have now created an environmental disaster when they diverted so much water from the Ural Sea to grow cotton that the sea has almost disapeared.

Woodpulp on the other hand, form northern forests is very very environmentally managed, and a sheet of good virgin paper, will last about 250 years. The real problem is recycled paper, which will last 30 years and creates far more polution to clean than the raw material took to create in the first place - Dave Calladine

In the woods with no extra water, use large leaf. At home/farm, your fingers. Then you wash them with water. Short of water in desert? See Muslim sanitation rules (use only left hand for asshole). In 18th century (and until recently in India) you would have a cloth that was immediately washed out in a bowl of water.
