Abstract

The invention discloses a degradable and environmentally-friendly biomass plastic bag. The plastic bag is made from, by weight, 60-75 parts of LDPE, 15-22 parts of plant starch, 6-8 parts of calcium carbonate, 3-5 parts of butanetriol, 7-12 parts of glass fibers, 7-14 parts of wheat straw powder, 5-8 parts of polylactic acid, 12-13 parts of vinyltrimethoxy silane, 6-9 parts of potassium sorbate, 5-8 parts of biphenyl diphosphite, 3-6 parts of a photosensitizer, 1-3 parts of a bactericide and 6-8 parts of diethyl phthalate. The plastic bag has the advantages of non-toxicity, no pollution, good environmental protection property, strong degradation ability, strong tensile strength, good tension, and no harmful substances after decomposition.

Description

technical field [0001] The invention relates to the technical field of plastic bags, in particular to a biodegradable environmentally friendly plastic bag. Background technique [0002] Plastic shopping bags are consumables in daily life, and China consumes a large amount of plastic shopping bags every year. While providing convenience to consumers, plastic shopping bags also cause serious waste of energy resources and environmental pollution due to excessive use and inadequate recycling. Especially ultra-thin plastic shopping bags are easily damaged and are mostly discarded at will. Become the main source of "white pollution". Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a biodegradable environmentally friendly plastic bag that is non-toxic, non-polluting, good in environmental protection, strong in degradation ability, strong in stretchability, good in tension, and free of harmful substances after decom...
