Biodegradable plastic bags are made of biodegradable materials, which can be completely decomposed into water and carbon dioxide under industrial composting conditions by the action of microorganisms, and are completely harmless to the environment. Its advantages are: 1, it is a renewable resource; 2, biodegradable, decomposed into water and carbon dioxide; 3, can be industrially composted 4, anti-bacteria and anti-mold. In addition, it has high strength, high transparency, good heat resistance and high plasticity. In the use of the basic can replace the ordinary pe plastic bags.
Photodegradable plastic bags are infiltrated with photosensitizers in the plastic, so that the plastic gradually decompose under sunlight, but in the end it only decomposes into tiny particles invisible to the naked eye, which actually still exist in nature, but more easily absorbed by people or animals into the body, which is harmful to the body. It belongs to an earlier generation of degradable plastic, which has been banned in many countries.
