Polylactide (PLA), is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material. Using supercritical CO2 autoclave foaming process to physically foam the modified PLA particles, a degradable E-PLA lightweight material can be obtained.
