Abstract

The invention provides a degradable plastic packaging material and a preparation method thereof, and relates to the technical field of packaging material production. The packaging material is preparedfrom, by weight, 50-60 parts of low density polyethylene, 30-40 parts of starch, 2-3 parts of vinyl tris(beta-methoxyethoxy)silane, 0.8-1.2 parts of a modifier, 8-12 parts of an ethylene-vinyl acetate copolymer, 5-8 parts of a butylene adipate-butylene terephthalate copolymer, 8-10 parts of methyl pentanol, 3-5 parts of alumina, 3-5 parts of zinc oxide, 4-6 parts of hydroxypropyl methylcellulose,4-6 parts of p-hydroxyphenyl lignin, 2-4 parts of a solubilizer and 2-4 parts of a plasticizer. The deficiencies of the prior art are overcome, and the mechanical properties and the molecular weightof the packaging material are reduced after the packaging material is discarded in order to effectively improve the degradation effect of the packaging material, so the packaging material is prone tobecome soft, and can be easily decomposed, and the packaging material also has a good degradation effect, thereby the environment pollution is reduced, and the packaging material is suitable for beingpromoted.

Description

technical field [0001] The invention relates to the technical field of packaging material production, in particular to a degradable plastic packaging material and a preparation method thereof. Background technique [0002] Packaging materials refer to the materials used to make packaging containers, packaging decoration, packaging printing, packaging and transportation to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Main packaging materials such as chemical fibers and composite materials, as well as auxiliary materials such as strapping, decoration, and printing materials. Packaging materials occupy an important position in the entire packaging industry and are the basis for developing packaging technology, improving packaging quality and reducing packaging costs. [0003] Plastic packaging materials are usually made of polyethylene, polypropylene, etc. as the main raw materials. Due to the hi...
