Problems solved by technology

While plastic packaging bags provide convenience, due to excessive use and inadequate recycling, they also cause serious waste of energy resources and environmental pollution.
In particular, ultra-thin plastic packaging bags are easily damaged, and most of them are discarded at will, becoming the main source of "white pollution"

Abstract

The invention discloses a plastic packaging bag, and belongs to the technical field of plastic products. The plastic packaging bag is made of components including, by weight, 100 parts of linear low-density polyethylene, 20-25 parts of polyolefin, 45-50 parts of corn straw fibers, 10-15 parts of chitosan, 30-45 parts of corn starch, 8-12 parts of titanium stearic acid, 1-5 parts of polyethylene wax and 20-30 parts of silicon carbide. Based on the linear low-density polyethylene and the polyolefin, the corn straw fibers, the chitosan, the corn starch, the titanium stearic acid, the polyethylene wax and the silicon carbide are added to obtain the novel durable, easily oxidized and degraded and environment-friendly plastic packaging bag.

Description

Technical field [0001] The invention belongs to the technical field of plastic products, and particularly relates to a plastic packaging bag. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material to produce various articles in daily life, and is widely used in daily life and industrial production. [0003] Plastic packaging bags are consumables in daily life, and a large amount of plastic packaging bags are consumed every year. While plastic packaging bags provide convenience, they also cause serious waste of energy and resources and environmental pollution due to excessive use and inadequate recycling. In particular, ultra-thin plastic packaging bags are easily damaged, and most of them are randomly discarded, becoming the main source of "white pollution". More and more countries and regions have restricted the production, sales and use of plastic packaging bags. In order to implement the scientific development concept ...
