Plastic film

Abstract

The invention relates to a plastic film. The plastic film comprises the following components in parts by weight: 40-60 parts of corn starch, 100 parts of polyethylene, 10-20 parts of polycarbonates, 12-15 parts of thylene-butylene polymers, 5-10 parts of polyethylene wax, 2-4 parts of an anti-oxygen, 0.5-1 part of an ultraviolet light absorber and 4.5-6.5 parts of cedarwood oil. The oxygen isolating and degradable plastic film provided by the invention can be decomposed automatically under the influences of oxygen enrichment and microorganisms, the abandoned film can be degraded and digested completely through the microorganisms in nature to generate carbon dioxide and water ultimately, and compared with LDPE (low-density polyethylene) plastic film with same thicknesses, the oxygen isolating property can be improved by 40%. The preparation method of the plastic film provided by the invention has the advantages that the process is simple, the production efficiency is high, the implementations of the industrialization is easy and the plastic film can be produced through common plastic film blasting machines.

Description

technical field [0001] The invention belongs to the field of plastic film materials, in particular to a plastic film. Background technique [0002] Degradable films not only have the functions and characteristics of traditional plastics, but also can be split and degraded in the natural environment through the action of microorganisms in soil and water or ultraviolet rays in sunlight after reaching the end of their service life, and finally re-enter the ecology in a reduced form. environment, back to nature. Domestically developed varieties have covered photodegradation, photobiodegradation, photooxidative biodegradation, high starch content biodegradation, high calcium carbonate filled photooxygen degradation, and full biodegradation. At present, there are many materials in the degradable material market, but they are roughly divided into photothermal degradable plastics and pure biodegradable plastics. Length, etc. cannot meet the actual physical performance requirements...

AI Technical Summary

Problems solved by technology

At present, there are many materials in the degradable material market, but they are roughly divided into photothermal degradable plastics and pure biodegradable plastics. However, the existing degradable products only consider one aspect of the degradation environment, and the physical and mechanical properties of the products are The length, etc. cannot meet the actual physical performance requirements of the final product
