What is the concept of 80 grams of copper paper or 100g of coated paper in the current market, 80 grams of coated paper, that is, the weight of one square meter of paper is 80 grams, 80g per square meter. In the same way, 90 grams, 108 grams, and 157 grams of coated paper are all the same.

Let's talk about the unit of the order, one ring of paper is equal to 500 sheets of fully open paper (full open paper is uncut coated paper).

The formula for calculating the weight of a piece of paper should look like this:

Length x Width x Gram Weight per square meter, for example, how much does a piece of coated paper weigh with a magnanimity of 157 grams?

A: 1194mm x 889mm x 157g m2=

Then one ream of paper is equal to 500 x the weight of a single sheet. In this way, it is easy to calculate how many reams a ton of paper is equal to: divide 1kg by the weight of 1 reams of paper to know the result.

Regular magnanimity paper (1194 x 889) coefficient (that is, length x width) =

Regular positive paper (1092 x 787) coefficient =

Therefore, when calculating, you only need to multiply the coefficient by the weight of the coated paper to get the weight of the sheet.

Paper conversion formula.

1.The unit of coated paper:

a.g: The weight of one square meter (length and width 2) = g is the weight.

b.Ream: 500 sheets of paper unit called: Ream (factory specification).

c.Tons: 1 ton = 1000 kg as usual units, which is used to calculate the paper price.

2.Specifications and names of coated paper:

a.Coated paper is most commonly available in four sizes:

1).Positive paper: centimeters long. Width cm.

2).Generous paper: centimeters long. Width cm.

3).Self-adhesive: length 765 cm. Width 535 cm.

4).Carbonless paper: There are specifications of positive and generous, but there is a loading paper. Medium paper. The price of the paper is different.

One inch = one line = gram.

One kilogram = pounds.

One pound = kilogram.

One yard = meter.

Positiveness: inches).

Generous: inches).

One ream = 500 sheets (pcs).

Price = length (m) width (m) gram weight (kg) ton price (yuan kg).

As of July 2021, ** in a pound.

Precautions for the use of paper.

Generally speaking, shredded paper processed by the shredder can be utilized. However, after the high-density shredder treatment, the paper powder that is cut into special shreds cannot be recycled, and in general, the best paper products are classified according to their different categories.

Paper cups and beverage cups cannot be separated from the paper because a layer of plastic film is attached to their surface (to prevent water seepage), and it is not easy to separate from the paper in the processing process.

**, postcards, carbon paper, receipts, note-memo paper, etc. are not allowed to ** also because of their complex composition, foreign matter can not be fully excluded during regeneration.

Specific problems are analyzed on a case-by-case basis, depending on the local situation.

Coated paper is a high-grade printing paper made of white paint coated with base paper. It is mainly used for printing the covers and illustrations of high-end books and periodicals, color pictures, various exquisite commodity advertisements, samples, commodity packaging, trademarks, etc.

Coated paper is also known as printing coated paper. A layer of white paint is applied on the surface of the base paper, which is processed by super calendering, which is divided into two types: single-sided and double-sided, and the paper surface is divided into two types: glossy surface and cloth texture. The surface of the paper is smooth, the whiteness is high, and the ink absorption and ink performance is very good.

It is mainly used for offset printing, gravure fine screen line printing, such as high-end albums, calendars, books and periodicals, etc. The disadvantage is that the powder is easy to stick and fall off after moisture, and cannot be stored for a long time.

The coated paper is flat paper, with a size of 787 1092mm, 880 1230mm, and a quantitative size of 70 250g square meters. Coated paper is divided into single-sided coated paper, double-sided coated paper, matte coated paper, and cloth coated paper. According to the quality, it is divided into three categories: A, B, and C.

The main raw materials of coated paper are coated base paper and coatings.

The requirements for coated base paper are uniform thickness, small elasticity, high strength and good water resistance. There are no spots, wrinkles, holes and other paper diseases on the paper surface, and the coatings used for coating are composed of high-quality white pigments, adhesives (such as polyvinyl alcohol, casein, etc.) and auxiliary additives.

This kind of paint with high fluidity and high solid content is thinly and evenly applied to the base paper by the coater, then dried, rolled into a roll shape on the reel, and then sent to the super calender for calendering and finishing, and finally slitting, paper selection, and packaging.

White printing paper such as offset paper and light paper is about 8,000 yuan a ton, newsprint is about 5,000 yuan a ton, and containerboard paper is about 4,000 yuan a ton, which has to be related to the specific needs of customers.

The price of cultural paper and packaging paper has been brushed and brushed. Since May, major domestic cultural paper enterprises and merchants have issued a number of price increase letters, and the price of Chinese paper has generally increased by 200 yuan tons, and the price of white cardboard has reached 1,000 yuan. The owner of a printing shop in Beijing said that the original price of white cardboard was 6,500 yuan, but now it is yuan, and his profit has dropped by almost 30 percent.

In this round of price increases, a number of paper companies in the first quarter of the financial report is bright.

Chemical composition of raw materials Plant fibers mainly contain:

1. Cellulose.

In cotton, the cellulose content is more than 90%; Wood, reeds, and reeds also contain 40 to 50% cellulose. From a papermaking point of view, cellulose should be retained as much as possible during the pulping process to improve pulp yield and paper strength.

2. Hemicellulose.

Among the plant fiber raw materials, the hemicellulose content in hardwood and grass raw materials can be as high as about 30%; In coniferous wood, it generally contains only about 20%; Less abundant in cotton. In order to improve the pulping yield and paper strength, some hemicellulose should also be retained as much as possible in the pulping process.

3. Lignin. In coniferous wood, the lignin content accounts for about 30%, while grass raw materials generally contain about 20%, and cotton and flax do not contain lignin.

Chemical pulping is the use of chemicals to dissolve part of the adhesive substances between cells, so that the fibers are separated from each other into pulp. The more lignin is in the raw material, the more difficult it is to make pulp and the more chemicals to be consumed.

Secondary components: In addition to the three main components of cellulose, hemicellulose and lignin, there are other components with less content, such as resin and ash. The content in the commonly used raw materials is not large, and it will not cause much difficulty to papermaking.

However, if the content is too much, some special requirements of the paper must be removed accordingly.

This is a score of paper, and there are too many papers. At present, white printing paper such as double-offset paper and light paper is about 8,000 yuan a ton, newsprint is about 5,000 yuan a ton, and containerboard paper is about 4,000 yuan a ton, which has to be related to the specific needs of customers.

Commonly usedCoated paper, its specifications and grams are often certain, generally speaking, the quantitative coated paper has grams of square meters.

You can choose the number of grams according to your own needs, generally speaking, the larger the number of grams of coated paper, the greater the weight of a single sheet. If it is a flat sheet packaging specification, there are 787 1092 (mm 1230 (mm)), therefore, when the printing plant selects and prints coated paper, it only needs to match the above two quantities.

Coated paper characteristics:The coated paper has a smooth surface, high whiteness, uniform distribution of paper fibers, consistent thickness, small elasticity, good elasticity and strong water resistance and tensile resistance, and the absorption and acceptance of ink are very good.

There are two types of coated paper: single and double-sided. Main uses: Mainly used for printing albums, covers, and postcards.
