Degradable environmentally-friendly plastic bag and method thereof

Abstract

The invention discloses a degradable environmentally-friendly plastic bag and a production method thereof. The degradable environmentally-friendly plastic bag comprises a bag body, and each bag body has three layers including an inner layer, an interlayer and an outer layer which are sequentially stacked; the inner layer comprises the following materials, in parts by weight: 80 parts of polyethylene, 7 parts of poly(propylene carbonate), 10 parts of starch and 3 parts of black color masterbatch; the interlayer comprises the following materials, in parts by weight: 50 parts of polyethylene, 20parts of polyhydroxyalkanoate, 4 parts of poly(propylene carbonate) and 10 parts of milky white color masterbatch; and the outer layer comprises the following materials, in parts by mass: 70 parts ofpolyethylene, 10 parts of poly(propylene carbonate), 8 parts of aliphatic polycarbonate, and 12 parts of gray color masterbatch. The plastic bag provided by the invention has the advantages of a simple formula, adaptability to more environmental degradation, better environmental protection, low costs, good product quality and long service life.

Description

technical field [0001] The invention relates to the technical field of plastic bags, in particular to a degradable environment-friendly plastic bag and a method thereof. Background technique [0002] Traditional plastic bags are non-degradable, and some degradable plastic bags are not very effective. The degradation situation is different in different places, because the environment is different, so there is a need for a degradable plastic bag that can better adapt to different environments. Make plastic bags more environmentally friendly and protect the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a degradable environmental protection plastic bag and its method, which has a simple formula, can adapt to more environmental degradation, better environmental protection, low cost, and good product quality , The advantages of long service life.
