Polylactic acid (PLA) is one of the biodegradable plastics. Its raw materials come from renewable plant fibers, corn, agricultural by-products, etc., and it has good biodegradability.
PLA has excellent mechanical properties, similar to polypropylene plastics, and can replace PP and PET plastics.
PLA can be decomposed into water, carbon dioxide, and methane by microorganisms existing in nature.
