Compared with traditional plastics, polylactic acid (PLA) can be degraded into CO2 and H2O by microorganisms and light. Its degradation products are non-toxic and harmless, and will not cause environmental pollution. The monomer that produces polylactic acid is lactic acid, which in turn can be produced by the fermentation of crops or agricultural and sideline products such as wheat, rice and sugar beet. Therefore, the raw material for the production of polylactic acid is renewable.

PLA raw materials come from a wide range of sources, and the products made from PLA can be directly composted or incinerated after use, and finally completely reduce CO2 and H2O, meeting the requirements of sustainable development. The good transparency, toughness, biocompatibility and heat resistance of PLA are the main reasons for its wide application. In addition, PLA is thermoplastic and can be applied in many fields. The products prepared with it, such as packaging materials and fibers, are mainly used in disposable products such as disposable tableware and packaging materials, car doors, footpads and seats, clothing, electrical appliances and medical and health (orthopedic internal fixation materials and non-removable surgical sutures, etc.) and other fields.
