       PLA主要成分乳酸大多通过淀粉等发酵制备得到，工艺和技术已经成熟。是无色、光滑的硬塑料，高强度、高模量，其力学性能与PS相似，拉伸以及弯曲模量高于HDPE，但是本身韧性较差。适宜注塑、吹塑、热成型、挤出、流延、熔融纺丝和静电纺丝等多种加工工艺。主要用于包装和纤维。     
       Lactic acid, the main component of PLA, is mostly prepared by fermentation of starch, and the process and technology are mature. It is a colorless, smooth hard plastic with high strength and high modulus. Its mechanical properties are similar to PS, and its tensile and flexural modulus are higher than HDPE, but its toughness is poor. It is suitable for various processing processes such as injection molding, blow molding, thermoforming, extrusion, casting, melt spinning and electrospinning. Mainly used for packaging and fibers. also be used as engineering plastics in machinery, chemical and other equipment, and is widely used in drainage boards.
