PLA Polylactic acid, also known as polylactide, belongs to the polyester family. PLA is a polymer obtained from the polymerization of lactic acid as the main raw material, the raw material source is sufficient and renewable, mainly corn, cassava and other raw materials. The production process of PLA is pollution-free, and the product can be biodegradable, realizing the cycle in nature, so it is an ideal green polymer material, PLA has many applications, can be used in extrusion, injection molding, film, spinning and other field.

Film biaxial stretching line, which are represented by poly(ethylene terephthalate) (PET) films, are currently the most widely used polymeric substrate materials in the fields of display technologies, electronic devices, storage media, electronic insulators, automobile, molding, package, printing and architecture. This widespread use is a result of the films possessing high strength, durability, transparency, flexibility and good surface properties.Information and telecommunications equipment have recently required more compactness and portability as well as excellent film properties, such as higher heat resistance and dimensional stability, especially in the field of electronics, environment and energy. It has been difficult for conventional biaxially stretched PET films to meet the future demand, and outstanding films with cost effectiveness are required.
