coated paper with pigment, adhesive and auxiliary materials is prepared, coated on the surface of cardboard by special equipment, dried and calendered to form a smooth and compact coating on the paper surface, thus obtaining coated paper with good surface performance and printing performance. Mostly used in cigarette cases, labels, cartons and so on.

offset paper

is mainly one-sided offset printing paper. The paper is white and smooth, but its whiteness, compactness and smoothness are lower than that of coated paper. Super calendered offset paper has better smoothness and tightness than ordinary calendered offset paper. After printing words and patterns, it can be pasted with yellow paperboard into cartons.

trademark paper

trademark paper has white paper surface and good printing performance, and is used to make trademark signs.

Kraft paper

includes boxboard paper, cement bag paper, high-strength corrugated paper and brown paperboard. Kraft paper is a kind of high-strength packaging paper made of softwood kraft pulp with tough texture, high strength and yellowish brown paper surface. It can be divided into single-sided gloss, double-sided gloss, striped and non-striped, and its quality requirements are slightly different. Kraft paper is mainly used to make small paper bags, document bags and inner packaging of industrial products, textiles and daily necessities. Kraft paper is divided into U, A and B3 grades.

corrugated paper 8g/mm double-sided offset printing paper corrugated paper is pressed into a corrugated shape in the production process. After being made into corrugated board, it will provide paperboard elasticity and flat compressive strength, and affect the vertical compressive strength and other properties. Corrugated paper, the paper surface should be flat, the thickness should be consistent, and there should be no paper defects such as wrinkles, cracks and holes, otherwise it will increase the broken ends in the production process and affect the product quality.

bag paper

similar to kraft paper, bag paper is mostly made of softwood kraft pulp, and it is also mixed with some bamboo pulp, cotton stalk pulp and rag pulp in China, so it has high mechanical strength and is generally used to make packaging bags for cement, pesticides, fertilizers and other industrial products. In order to meet the requirements of filling, bag paper requires certain air permeability and large elongation.

cellophane

cellophane is a widely used lining paper and decorative packaging paper. Its transparency makes people see the goods inside at a glance, and after the surface is coated with plastic, it has the properties of moisture-proof, water-proof, air-tight and heat-sealing, which plays a good role in protecting the goods. Compared with ordinary plastic film, it has the advantages of no static electricity, dust prevention and good kink. Cellophane is available in white and color.

white cardboard

is a kind of flat paper with smooth surface and firm texture.

white cardboard

white cardboard is divided into double-sided white cardboard and single-sided white cardboard. Double-sided white cardboard is only used for packaging high-grade goods. Generally, single-sided white cardboard is mostly used in cartons, such as making outer packaging boxes for cigarettes, cosmetics, medicines, food, stationery and other goods.

composite paper

paper and cardboard are laminated with other plastics, aluminum foil, cloth, etc. with adhesive to obtain composite processing paper. Composite processing paper can not only improve the appearance and strength of paper and paperboard, but also improve the waterproof, moisture-proof, oil-resistant, airtight and fragrant-keeping properties, and at the same time, it will also obtain heat sealing, light blocking and heat resistance. The methods of producing composite paper include wet method, dry method, hot melting and extrusion compounding.
