Hello, there are many varieties of paper, and the classification methods are also inconsistent.

1. Handmade paper: It is mainly made by manual operation, using the curtain net frame and manually fishing it out one by one. It has a soft texture and strong water absorption, and is suitable for ink writing, painting and printing, such as Chinese rice paper. Its production accounts for a small proportion of the total production of modern paper.

2. Coated paper: Also called pink paper, it is relatively glossy on both sides. It is often used for picture albums, posters, etc. It has fine printing and is commonly used in 105-300g. However, since it is used in all picture albums, the used paper is a bit shabby. Now many designers don’t like to use this kind of paper.

3. Matt pink paper: Compared with coated paper, both sides are non-reflective and can be used for albums and posters. The common ones are 105-300g. I think it is quite high-end, but it is also used more now. Well, generally speaking, picture albums basically use coated paper and matte pink paper.

4. Gray cardboard: often used in packaging boxes because the back is gray and commonly known as gray cardboard. The most common size is 250-400g. It is also often used for mounting paper and is commonly known as cardboard. Dong, the packaging box made in this way is more protective for the product.

5. White cardboard: Compared with gray cardboard, the back is white, but the paper center on the side is gray. Common 250-400g lt; single pink card gt; white on the front and white on the back. White, the paper quality is better than white card, hard enough, usually 250-400g.

6. Box cardboard: Also known as hemp cardboard, it is a relatively sturdy cardboard used in cartons. It is widely used for shipping books, department supplies, radios, televisions, machine parts and food, etc. Basis basis is 200 g/m2, 310 g/m2, 420 g/m2 and 530 g/m2. Smooth surface and good mechanical strength.

7. Offset paper: formerly known as "Daolin paper", it is paper for books and periodicals used by offset printing machines. Suitable for printing single-color or multi-color book covers, text, inserts, pictorials, maps, posters, color trademarks and various packaging materials. Offset printing paper is divided into special size, No. 1 and No. 2, with basis weight from 70 g/m2 to 150 g/m2. Pulp has high strength and printability. Offset printing is a relatively high-end printing paper for books and periodicals. It has high requirements on contrast, stretch rate and surface strength. The acidity and alkalinity should also be close to neutral or weakly alkaline so as not to affect the paper used for printing. The basis weight is 40 g/square. m to 80 g/m2. In recent years, we have successfully trial-produced low-quantity offset printing newsprint and offset printing book and periodical paper for use in offset printing paper and books and periodicals.

8. White cardboard: also known as manila paper, it is a white, relatively high-end packaging cardboard. It is used to print children's educational pictures and trademarks for stationery, cosmetics, and medicines. Basis basis is 200 g/m2 to 400 g/m2. The thickness is consistent, lint-free, powder-free, tough, and not easy to break when folded.

9. Straw cardboard: also known as yellow cardboard or horse manure paper, it is yellow packaging cardboard. It is mainly used for the packaging of goods, the cover lining of paper boxes and book boxes. Basis basis is 200 g/m2 to 860 g/m2. The commonly used ones are No. 8 420 grams, No. 10 530 grams, and No. 12 640 grams. Strawboard requires tight and solid quality, smooth paper surface, and certain mechanical strength and toughness.

10. Letterpress paper: A kind of paper suitable for letterpress printing machines to print the text of various books, cultural and sports supplies and magazines. The basis weight is 52 g/m2 and 60 g/m2, available in roll paper and flat paper, with a smoothness of 30 meters and an opacity of not less than 88%. Letterpress printing paper is widely used for books and periodicals. It is slightly smoother than newsprint and has a longer shelf life. However, it is prone to lint and powder loss and is not suitable for printing books and periodicals using offset printing. This kind of paper bleeds easily when writing on it.

11. Special paper: Generally refers to special paper, such as butter paper and steel antique paper. The quality is good but the price is expensive. Because there are too many categories, I will not introduce them one by one.

Hope it is useful to you.
