PBAT - is a copolymer of aliphatic (butanediol adipate) and aromatic (butanediol terephthalate)
It has excellent degradability and good mechanical properties
PLA - polylactic acid, is made from starch raw materials proposed by renewable plant resources (such as corn, cassava, etc.).It has good biodegradability, and can be completely degraded by microorganisms in nature under specific conditions after use, and eventually generate carbon dioxide and water.
These two are now in the true sense of biodegradable plastic bags
