Problems solved by technology

[0005] In the prior art, for the purpose of environmental protection, biological materials are mostly used for production, which is beneficial to the degradation of the product. However, the traditional composite technology of plastic film needs to go through the process of high temperature and high pressure drying before it can be composited. It will destroy the fibrous tissue and affect the quality of the product

Embodiment Construction

[0013] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0014] A kind of composite preparation method of novel environment-friendly fiberglass paper, comprises the following steps:

[0015] S1. The coating machine adopts the method of reverse coating, lightly coats the water-based environmental protection coating on the surface of the cellophane, and completes the coating treatment by infrared drying;

[0016] S2. Composite the treated cellophane and printing paper by reverse coating and drying, and then cold pressing to complete the surface treatment of printing and packaging;

[0017] S3. The surface of the raw material cellulose cellophane does not need to be treated. The cellophane and printing paper are compounded by the roll PUR professional equipment with precision coating and close-distance cold pressing to ...

Abstract

The invention relates to a composite preparation method for novel environment-friendly cellulose cellophane. The composite preparation method comprises the following two modes: 1, a coating machine adopts a reverse coating mode to lightly coat the surface of cellophane with a water-based environment-friendly coating, then coating treatment is finished in an infrared drying mode, then the treated cellophane and printing paper are compounded through professional equipment in a manner of precise reverse coating, drying and close-range cold pressing, and printing and packaging surface treatment is completed; and 2, the cellophane and the printing paper are compounded through drum PUR professional equipment in a precise coating and close-distance cold pressing mode, and printing and packaging surface treatment is completed. The preparation method can increase the surface glossiness of the product; full-degradable materials are adopted, and national environmental protection standards in China are met; the product is colorless, tasteless and nontoxic, and has high temperature resistance, water resistance moisture resistance and high barrier performance; and the above two modes can completely replace a traditional plastic film packaging film covering technology.

Description

technical field [0001] The invention relates to the technical field of plastic film compounding, in particular to a novel compound preparation method of environment-friendly fiberglass paper. Background technique [0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as laminations. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0003] The composite processing method of various plastic films is disclosed in the prior art, such as Chinese invention patent (publication number: CN112898665 A) a kind of p...
