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"
With the increase in the use of plastic bags, more and more problems have emerged. The used plastic bags are not easy to recycle and degrade. These problems have greatly troubled people.

Abstract

The invention discloses an environment-friendly plastic food packaging bag. The environment-friendly plastic food packaging bag is prepared from, by weight, 40-50 parts of polyethylene resin, 15-20 parts of plant fiber, 5-10 parts of corn starch, 0.4-0.8 part of a lubricant, 0.1-05 part of a coupling agent, 0.4-0.8 part of a filler, 1-3 parts of a natural antibacterial agent, 2-5 parts of citric acid and 2-5 parts of a pH modifier. The polyethylene resin is taken as the main raw material aided with the plant fiber and multiple functional additives to prepare the plastic food packaging bag which is tough and durable, reusable, hygienic, toxic free and environment friendly, dampproof, dustproof and mildewproof and suitable for various food packaging; the starch and calcium carbonate are added, degradation is accelerated, and pollution of the environment is greatly reduced.

Description

technical field [0001] The invention relates to the field of film processing, in particular to an environment-friendly plastic food packaging bag. Background technique [0002] The plastic bag made of plastic film is light, thin, impermeable, strong, and low in cost. It is a good packaging material. The use of plastic bags brings great convenience to people's lives. 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". With the increase in the use of plastic bags, more and more problems have emerged. The used plastic bags are not easy to recycle and degrade. These problems have greatly troubled people. Consistent with the concept of advocating green environmental protection, how to find a plastic den...
