Corrugated paper

Corrugated paper is made of corrugated cardboard as the core layer, with one or more layers of hard cardboard. It has good compression resistance, folding resistance and cushioning properties, and can be made into cartons of various specifications. Corrugated paper is divided into three categories: A, B, and C, and the commonly used is A-type paper. There are two commonly used cardboards: single-sided corrugated paper (single-sided corrugated cardboard) and double-sided corrugated paper (double-sided corrugated cardboard).

In packaging, cartons are usually made of double-sided corrugated cardboard because it has good cushioning properties, can effectively protect goods from damage, and has low cost. In addition, it can also prevent the goods from being soiled. If the carton is soiled, you can turn it over and clean it. Even the smallest label can be easily done on the carton. Therefore, it can greatly improve the efficiency of commodity packaging.

Coated paper

Coated paper is a high-grade paper made of wood, bamboo, cotton, hemp and other plant fibers as the main raw materials, with a small amount of fillers and adhesives added, and made through a special pulping and papermaking process. It is divided into two varieties: white coated paper and colored coated paper. White coated paper is generally opaque, but some are transparent. White coated paper can be divided into two types: one is coated white copper and the other is uncoated white copper. Both types of coated paper have very good printing effects. In addition, since white copper has a certain degree of waterproofness, its packaging products are often packaged in non-waterproof polyvinyl chloride film bags.

Colored coated paper is a highly transparent, translucent paper, generally used for printing high-end picture albums, posters and other products, and can also be used for printing color leaflets, trademarks and other products. Colored coated paper is favored by consumers and printing factories for its rich colors and good printing effects. It is widely used in the printing and packaging industry.

White cardboard

White cardboard is a special paper used to make book and magazine covers. White cardboard is divided into three types according to its fiber morphology: wood pulp white cardboard, bamboo pulp white cardboard, and cotton pulp white cardboard. It is divided into three types according to the raw materials used: wood pulp white cardboard.

Generally speaking, the quality of newsprint (or book and magazine paper) is higher than that of white cardboard, so more newsprint is used for printing than white cardboard. It is shown in a translucent state, and the printing ink is required not to penetrate between the paper fibers, otherwise it will affect the printing quality. Therefore, general book and magazine paper requires good ink quality. Book and magazine covers made of white cardboard have a high collection value. Most of the book and magazine covers seen on the market are printed on white cardboard, which gives people a sense of nobility and elegance and is an indispensable part of high-end packaging products.

Kraft paper is most suitable for making envelopes, letter paper and trademarks, etc. It can be used for printing and packaging. The main use of kraft paper is as a trademark.

It has good stiffness of paper, fine texture, smooth surface, opaque, and has a certain stiffness and transparency. It is resistant to water, moisture, wear and folding. Therefore, corrugated board is mostly used to package various items.
