PET PLA PC single screw co-extrusion sheet unit
Summary: The production line adopts a new extrusion system-co-directional parallel batching and mixing twin-screw extruder, which has the characteristics of starvation feeding, high-efficiency mixing, devolatilization and exhaust, self-cleaning performance, building block combination and stable extrusion. It fully applies its special performance, is connected with auxiliary film forming machines, and has the advantages of integrating mixing and forming, thus saving space, reducing labor and saving energy. In processing PET/PLA sheets, through the special optimization design of the vacuum exhaust system, it is not necessary to configure the raw material drying system. On this basis, if the crystallization device is added, the sheet products will be more competitive.
Key words: twin-screw, sheet machine

Product introduction:
Polyester (PET) calendered sheet and board production line: two or three extruders can be used to process APET, modified PETG and special CPET. PET has an increasing market demand due to its excellent transparency, rigidity, good thermoformability and recyclability. Its products are usually 2-3 layers, and the middle layer contains high-specific recycled materials, the outer layer is usually a pure resin and an anti-blocking agent or stabilizer or the like is added. PET/PE composite sheet is the latest trend in the development of PET packaging sheet, which is widely used in forming, filling and sealing packaging production lines.Application as a substrate, in which PET can provide excellent thermoformability, transparency, stiffness and good barrier properties, PE is to ensure heat sealing and peeling performance. In addition, PET can also be laminated with EVOH/PE to achieve superior barrier properties.
