Polylactic acid (PLA) is a polymer prepared by polymerization with lactic acid as the main raw material, commonly known as corn plastic, which is fully sourced and can be regenerated, mainly from L-lactic acid produced by corn and cassava. A new type of biodegradable polyester material was prepared by Polycondensation, cracking, purification, polymerization and other technological processes.The production process of polylactic acid is pollution-free, and the products can be biodegraded to realize the cycle in nature, so it is not only an ideal green polymer material, but also a high-tech environmental protection product encouraged by the state. It is widely used in the shell of electronic products, auto parts, medical devices, clothing fiber, agricultural plastic film, food packaging, tableware and other fields.
Jinwei mechanical PLA sheet extrusion production line is suitable for the production of PLA (polylactic acid) and modified PLA. PLA (polylactic acid) is derived from plant resources and can be directly used in extrusion molding. PLA and hydrolytic PLA are widely used in all kinds of food packaging and hardware packaging because of their biodegradability, composting, recycling and so on. Equipped with melt metering pump quantitative extrusion, speed and pressure closed-loop control, so that the thickness of the sheet is uniform. The roller is driven independently, and the linear speed of each roller is controlled synchronously. The whole machine adopts the automation of PLC control, actual parameter setting, data operation, feedback, alarm and so on.
