Problems solved by technology

At present, synthetic paper labels are made of uncoated PP synthetic paper. Since there is no coating that is easy to absorb ink, the molten carbon ribbon coating cannot be completely and quickly absorbed during ribbon printing, resulting in blurred printing patterns and easy to damage barcodes. Read, low color density values ​​with white spots

Abstract

The invention relates to a coated matte PP synthetic paper, which comprises PP synthetic paper and a coating layer coated on the surface of the PP synthetic paper. With the weight part of kaolin as the benchmark, the coating layer comprises the following raw materials by weight: 100 parts of kaolin, 0.8 part of a dispersant, 20-60 parts of an adhesive emulsion, 1-2 parts of a water repellent agent, 0.8 part of a pH regulator, 0.2-0.8 part of a defoamer and 80-150 parts of water. The paint of the formula provided by the invention is coated on the PP synthetic paper, the prepared coated PP synthetic paper is suitable for carbon band heat transfer printers of different types, at the same time has good matching properties with wax-based carbon band, mixed carbon band and resin-based carbon band, and has good waterproof and anti-ultraviolet performance, and better printing effect.

Description

technical field [0001] The invention relates to a coated matte PP synthetic paper and a preparation method thereof, belonging to the technical field of paper product processing. Background technique [0002] Synthetic paper is a new type of plastic material product, and it is also an environmentally friendly product. It has the characteristics of light specific gravity, high strength, tear resistance, good printability, shading, anti-ultraviolet, durable, economical and environmentally friendly. Since the production process of synthetic paper is non-polluting, it can be 100% recycled and recycled, which is a major reform of modern paper production. At present, PP synthetic paper is mainly used for clothing bags, handbags, woven bags, offset printing, screen printing, advertising inkjet, books, printed trademarks, etc., of which advertising inkjet accounts for 40%, printed trademarks account for 15%, and woven bags , offset printing, and screen printing accounted for 10% eac...
