PLA (polylactic acid) is a new biodegradable material,use recycle plant material (corn material) of starch raw materials to make.Glucose is obtained from starch by saccharification,then High purity lactic acid was produced by fermentation of glucose and certain strains.then polylactic acid with certain molecular weight was synthesized by chemical synthesis.It has good biodegradable function,it can be degrade to CO2 and H2O,It will not do harm for the environment.Its a Eco-friendly material
