General Printing Paper Overview

Coated paper is made of pigments, adhesives and auxiliary materials. It is coated on the surface of cardboard through special equipment. After drying and calendering, it forms a smooth and dense coating on the surface of paper to obtain good surface properties and printing performance. Coated paper. Used in cigarette cases, labels, paper boxes, etc. The most commonly used paper, the surface gloss is good, suitable for a variety of color effects.

Offset paper is mainly single-sided offset printing paper. Paper is white and smooth, but whiteness, tightness and smoothness are lower than coated paper. Super-calendered offset paper, its smoothness and tightness is better than ordinary calendered offset paper, printed with text, and can be pasted with yellow cardboard into a carton.

Traders of the trademark paper are white and have good printing performance and are used to make trademark marks.

Kraft paper includes cardboard, cement bag paper, high-strength corrugated paper, and brown cardboard. Kraft paper is a high-strength wrapper made of softwood, sulphate, and brown with strong texture, and can be divided into single-sided light, double-sided light, striped, and no stripe. The quality requirements are slightly different. Kraft paper is mainly used for the production of small paper bags, document bags and industrial products, textiles, daily necessities inside packaging. Kraft paper is divided into U, A, B3 grades.

Corrugated corrugated paper is pressed into a corrugated shape during the production process. After the corrugated board is made, it will provide the cardboard with elasticity, flat compressive strength, and affect the vertical compressive strength and other properties. Corrugated paper, paper is flat, the thickness should be the same, can not have wrinkles, cracks and holes and other paper diseases, otherwise increase the production process of breakage failure, affect product quality.

Paper bag paper paper paper is similar to kraft paper, and is mostly produced from softwood kraft pulp. Domestically, it is also blended with some bamboo pulp, cotton stalk pulp, and broken cloth pulp. Therefore, the paper bag paper has high mechanical strength and is generally used to make cement. Packaging bags for pesticides, fertilizers and other industrial products. To meet the requirements for filling, paper bags require a certain degree of breathability and greater elongation.

Cellophane cellophane is a widely used liner and decorative packaging paper. Its transparency makes people look at the contents of the product at a glance. After the plastic surface is coated, it is also moisture-proof, impervious to water, airtight, and heat-sealed. It plays a good role in protecting the product. Compared with ordinary plastic film, it has the advantages of no static electricity, dust, and good kink. Cellophane has white, color and so on.

White cardboard is a flat sheet of paper with a smooth surface and firm texture.

White paperboard is divided into double-sided white paperboard and single-sided white paperboard. Double-sided white paperboard is used only for packing high-end goods. Generally, the paperboard is mostly made of single-side white paperboard, such as cigarettes, cosmetics, medicines, food, stationery and other goods. Outside the box.

Composite paper is laminated with paper, paperboard and other plastics, aluminum foil, cloth, etc. with an adhesive to obtain a composite processed paper. Composite processing paper can not only improve the appearance and strength of paper and paperboard, but also improve the performance of waterproof, moisture-proof, oil-proof, air-tight and fragrant, etc. At the same time, it will also obtain heat-sealing, light-blocking and heat-resistance. The methods for producing composite paper include wet, dry, hot-melt and extrusion composite processes.

Printing paper is designed for printing paper. According to use can be divided into: newsprint, books and papers, cover paper, security paper and so on. According to the different printing methods can be divided into letterpress printing paper, gravure printing paper, offset printing paper.

Color printing paper mainly includes color printing paper boxes and color printing paper boxes.

The moisture-proof paper is a wrapping paper made by coating asphalt between two layers of raw paper. It is mainly used for moisture-proof packaging cigarettes and can also be used as fruit packaging. Moisture-proof paper has a certain moisture-proof ability, its moisture-proof rate is at least above 15%, good moisture-proof paper is coated evenly, adhesion is firm, there is no paper layer dehiscence and asphalt penetration phenomenon, heat-resistance is not lower than 85 degrees, and should not be There is odor, so as not to affect the quality of cigarettes, but now the cigarette packaging paper is not used.
