Polylactic acid (PLA) is a new type of bio-based and renewable biodegradable material, which is made using starch raw materialsproposed by renewable plant resources (such as corn, cassava, etc.). Starch raw materials are obtained through saccharification to obtain glucose, and then fermented with glucose and certain bacteria to produce high-purity lactic acid, and then a polylactic acid of a certain molecular weight is synthesized by a chemical synthesis method. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under specific conditions, and eventually generate carbon dioxide and water without polluting the environment. This is very beneficial to protecting the environment and is a recognized environmentally friendly material.
