Fully degradable packaging bag refers to the complete degradation of plastic packaging bags into water and carbon dioxide. The main source of this fully degradable material is processed from corn, cassava, etc. into lactic acid, which is PLA.
Polylactic acid (PLA) is a new type of biological substrate and renewable biodegradable material. Starch raw materials are glucose obtained through saccharification, and then fermented with glucose and certain bacteria to produce high-purity lactic acid, which is then synthesized by chemical synthesis. Molecular weight polylactic acid. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under certain conditions, and eventually generate carbon dioxide and water without polluting the environment. This is very beneficial to protecting the environment and is an environmentally friendly material for workers.
