Problems solved by technology

The laser mold needs to be packaged during transportation. The packaging film in the prior art has poor wear resistance and cannot protect the laser mold well, and most of the packaging films in the prior art have a single-layer structure , and the cushioning effect and toughness are not up to the requirements, and cannot meet the needs of the existing technology. Therefore, designing a plastic packaging film for laser molds with good cushioning effect, high wear resistance and high willpower performance is an urgent need to solve in the prior art. The problem

Abstract

The invention provides a plastic packaging film used for laser moulds. The plastic packaging film is composed of an inner film, a buffer layer, and an outer film; the inner film comprises, by weight, 80 to 120 parts of polyethylene resin, 60 to 90 parts of Low density polyethylene, 30 to 60 parts of high density polyethylene, 20 to 40 parts of polyvinyl chloride, 10 to 30 parts of nylon, 10 to 30 parts of an aluminum-based layered nanomaterial, 15 to 35 parts of cellulose, 2 to 8 parts of a phosphite ester stabilizer, 3 to 8 parts of acetyl tributyl citrate, 1 to 6 parts of benzoyl peroxide; the buffer layer is prepared from polystyrene foam plastic; and the outer film is prepared from, by weight, 60 to 90 parts of a polyolefin copolymer, 15 to 35 parts of polypropylene, 20 to 40 parts of polyolefin elastomer, and 5 to 15 parts of calcium silicate. The plastic packaging film is high in tensile strength, hardness, and wear resistance, and can be used for packaging moulds, such as laser moulds, with corner angles so as to protect the moulds from pollution and wearing.

Description

technical field [0001] The invention relates to the field of packaging films, in particular to a plastic packaging film for laser molds. Background technique [0002] At present, with the wide application of plastic products in my country, the demand for plastic films is gradually increasing. The laser mold needs to be packaged during transportation. The packaging film in the prior art has poor wear resistance and cannot protect the laser mold well. Most of the packaging films in the prior art have a single-layer structure. , and the buffering effect and toughness are not up to the requirements, and cannot meet the needs of the existing technology. Therefore, designing a plastic packaging film for laser molds with good buffering effect, high wear resistance and willful performance is an urgent need to solve the existing technology. The problem. SUMMARY OF THE INVENTION [0003] In order to solve the technical problems existing in the background technology, the present in...
