Polylactic acid, also known as polylactide, belongs to the polyester family. Polylactic acid (PLA) is a polymer obtained by polymerization of lactic acid as the main raw material. The raw material source is sufficient and can be recycled. It mainly uses corn and cassava as raw materials. The production process of PLA is pollution-free, and the product can be biodegraded to realize the cycle in nature, so it is an ideal green polymer material.
Polylactic acid has good thermal stability, processing temperature 170~230ºC, good solvent resistance, can be processed in a variety of ways, such as extrusion, spinning, biaxial stretching, injection blow molding. Products made of polylactic acid are not only biodegradable, but also have good biocompatibility, gloss, transparency, feel and heat resistance. They also have certain bacterial resistance, flame retardant and UV resistance, so they are widely used as packaging materials, fibers and nonwovens, etc. At present, it is mainly used in clothing (underwear, outerwear), industry (construction, agriculture, forestry, paper making) and medical and health fields
