PLA Sheet Extrusion Line,PLA Degradable Sheet Production Machine
1.Introduce of PLA sheet
Also known as polylactide, belongs to the polyester family. Poly (lactic acid) is a polymer obtained from the polymerization of lactic acid as the main raw material, which is usually called corn plastics. It has sufficient sources and can be regenerated. It is a new type of biodegradable polyester material made from l-lactic acid produced by corn and cassava through condensation, cracking, purification, polymerization and other technological processes. Pollution-free production process of poly (lactic acid) (PLA), and the product can be biodegradable, implementation cycle in nature, so it is the ideal green polymer material, and it also encourages the development of high-tech environmental protection products. It is widely used in electronic product shell, auto parts, medical equipment, clothing fibers, agricultural plastic films, food packaging, tableware, etc.

2.Introduce of PLA sheet production line
Gwell PLA sheet extrusion line is suitable for PLA(PLA) and modified PLA. PLA is derived from plant resources and can be directly used for extrusion molding. PLA and soluble PLA are widely used in various food packaging and hardware packaging due to their characteristics of biodegradability, composting and recycling. Rollers can independent drive. The whole machine adopts PLC control, automation of actual parameter setting, data operation, feedback, alarm and other functions.

(1)Twin-screw combination technology
Years of experience in R&D and design of twin-screw configuration are optimized and combined with advanced software technology. Special double-threaded elements and unique screw combinations can realize conveying plasticization, mixing and kneading, shearing and dispersing, homogenizing, exhausting, pressure building and extrusion and various functions. Especially for the removal of crystal water inside the PLA material, it has a very high efficiency. The specially designed exhaust port does not emit material, and is free and unobstructed. It realizes low-temperature extrusion and avoids thermal degradation of PLA;
(2)Vacuum exhaust technology
Multi-stage forced exhaust is efficient and safe to ensure that the PLA material will not be hydrolyzed or crystallized during the melting and plasticizing process. Special three-stage vacuum exhaust technology and oil-gas separation technology, super large pumping capacity and super high vacuum, greatly reduce the viscosity reduction of PLA.
(3) Spiral flow channel technology inside the high-strength roller
The internal spiral flow channel structure design of the high-strength roller is equipped with a water temperature control system, so that the roller has precise temperature control and efficient heat transfer effects;
