Green plastic bags are short for biodegradable plastic bags. With the development of science and technology, various types of materials that can replace traditional PE plastics appear, including PLA, PHAs, PBA, PBS and other polymer materials. Can be a perfect alternative to traditional PE plastic bags. Currently, environmental protection plastic bags have been widely used: supermarket shopping bags, continuous roll bags, and plastic film have large-scale applications in China. In Jilin Province, PLA (polylactic acid) has been used as a substitute for traditional plastic bags in the entire province, and good results have been achieved. Starch-based biodegradable plastic bags in Sanya, Hainan Province have also entered large-scale use in supermarkets and hotels.
