Dry-free crystallization and exhaust type-co-rotating parallel twin-screw sheet extrusion production line: It has the characteristics of low energy consumption, simple process, and convenient equipment use and maintenance. The flexible combination of the screw structure reduces the viscosity drop of the PET resin, the symmetrical roller improves the cooling efficiency while improving the production capacity and the quality of the sheet, and multiple sets of feeding devices reasonably control the ratio of new material, returned material, color masterbatch, etc. , the produced sheets can be used in the fields of blister printing and packaging. ▶PET Single-layer/Multi-layer Sheet Extrusion Production Line Equipment PET sheet is widely used in the outer packaging of cosmetics, medicines, tobacco and alcohol, etc.; the outer packaging of general commodities and the fields of stationery, pendants, advertising, posters, various cards, elevators, etc.; electronic trays, blister trays for seedling t
