Polylactic acid (PLA) is a new kind of biobased and renewable biodegradable material, which is made from starch proposed by renewable plant resources (such as corn and cassava). Starch raw materials obtained glucose through saccharification, and then fermentation of glucose and certain strains to produce high purity lactic acid, and then through chemical synthesis method to synthesize polylactic acid of a certain molecular weight. It has good biodegradability and can be completely degraded by microorganisms in the nature under specific conditions after use, resulting in carbon dioxide and water, which does not pollute the environment. This is very beneficial to the protection of the environment and is recognized as an environmentally friendly material.
