Abstract

The invention discloses an environment-friendly plastic packaging bag and a processing method thereof, and belongs to the technical field of plastic packaging bag processing, and the environment-friendly plastic packaging bag is prepared from the following components: linear low density polyethylene, polyvinyl chloride, EPI, corn starch, modified soybean starch, modified montmorillonite powder, calcium stearate, epoxidized soybean oil, ferrocene, an antioxidant, polyethylene wax, chitosan and polylactic acid. The prepared plastic packaging bag is good in comprehensive use quality, and the processing method is simple, easy to popularize and suitable for large-scale batch production.

Description

technical field [0001] The invention relates to the technical field of plastic packaging bag processing, more specifically, it relates to an environment-friendly plastic packaging bag and a processing method thereof. Background technique [0002] In daily life, when people buy goods, they will use various packaging bags, the most commonly used of which are plastic bags, plastic bags are made of plastic materials such as polyethylene, which have the advantages of light weight and low price, and are very popular. Consumers and manufacturers welcome it, but because general plastic bags have a long degradation cycle and are difficult to handle, they have a great impact on the environment, so people are focusing on research and development of degradable plastic bags. [0003] The application number is: 201810385634.1, which discloses a degradable packaging plastic bag film and its preparation process. The plastic bag film produced by it is degradable, and has the characteristics ...
