Double layer film extruder is specially used for the production of high pressure polyethylene, low pressure polyethylene, degradable plastics, recycled plastics, and with a folding device for blowing vest bag or flat pocket. The forming clips can be raised and lowered at will, making it easy to operate and ensure product quality. The device is compact, easy to operate, and occupies little space. It is an ideal equipment for professional production of plastic film.
The die is plated hard, whose structure is spiral mandrel type. The extruded molten material is uniform, and the blown film has good surface finish; the air-cooling device has a labyrinth type, and the air output is uniform, and it is cooled by circulating water. Thereby the blown film achieves a good transparency effect. The winding device adopts pressure friction winding or center winding, which is adjusted by torque motor, smooth and rewinding.
