Abstract

The invention discloses a degradable environment-friendly bag for substituting non-degradable plastic bags. The degradable environment-friendly bag can be gradually and completely degraded within 170-350 days when buried in soil, thereby solving the problem of white pollution and avoiding environmental pollution. According to the degradable environment-friendly bag, by means of the degradation initiating effects of plant microorganism of bamboo, so that degradation of PE (polyethylene) can be promoted. Especially when buried in soil and under dark and moisture conditions, the plant microorganism of the bamboo can promote growth of microorganism and bacteria and accelerate degradation of the PE. Meanwhile, the degradable environment-friendly bag can be degraded in an oxygen-free or micro-oxygen environment and avoid degradation in an oxygen environment, thereby avoiding influence on storage and usage. When treated through burning, the degradable environment-friendly bag can avoid generating black smoke, pungent smell and toxic and harmful substance during burning; the burnt ash is grey, is soluble in water and avoids toxic and harmful residues.

Description

technical field [0001] The invention relates to a storage bag and a preparation method thereof, in particular to a degradable environmental protection bag and a preparation method thereof. Background technique [0002] At present, shopping bags and packaging bags used in various industries such as supermarkets, homes, offices, industries, and agriculture are all made of polyethylene as the main raw material. Although these materials have excellent physical properties, they cannot be degraded, and the remaining fragments have a great destructive effect on the soil and the environment. A large amount of black smoke and harmful gases produced during incineration also have great damage to the human body, and at the same time destroy the atmospheric environment. If it is disposed of by deep burial, it will not be easily degraded for 50 to 100 years, causing serious white pollution and a series of adverse problems. [0003] In order to solve the contradiction between the product...
