PLA (Polylactic Acid) Environmentally Friendly Degradable Sheet Production Line

PLA（聚乳酸）是一種新型的生物基及可再生生物降解材料，使用可再生的植物資源（如玉米、木薯等）所提出的淀粉原料制成。聚乳酸的生產(chǎn)過(guò)程無(wú)污染，而且產(chǎn)品可以生物降解，實(shí)現(xiàn)在自然界中的循環(huán)，因此是理想的綠色高分子材料。聚乳酸的熱穩(wěn)定性好，加工溫度170～230℃，有好的抗溶劑性，由聚乳酸制成的產(chǎn)品除能生物降解外，生物相容性、光澤度、透明性、手感和耐熱性好，還具有一定的耐菌性、阻燃性和抗紫外性，因此用途十分廣泛，可用于水果，蔬菜，雞蛋，熟食和烘烤食品的硬包裝，也可用于三明治，餅干和鮮花等商品的包裝。

PLA (Polylactic Acid) is a novel biobased and renewable biodegradable material made from starch raw materials proposed by renewable plant resources such as corn and cassava. The production process of PLA is non-polluting, and the product can be biodegraded to achieve circulation in nature, so it is an ideal green polymer material. PLA has good thermal stability, processing temperature of 170-230℃, with good solvent resistance. Products made of PLA have the advantage of biodegradability, gloss, transparency,good feel and heat resistance. It also has good antibacterial, flame retardant and UV resistance, so it can be used in rigid packaging of fruits, vegetables, eggs, cooked foods and baked goods. It can also be used for the packaging of sandwiches, biscuits and flowers,etc.
