It is used to blow PE(HDPE LDPE) film, which is widely used for laminating film, packing film, agriculture film, film for textile, clothing bag etc. The main motor is controlled by inverter, which not only increase the stability for speed adjustment, but also save 30% energy. Both the screw and barrel adopt 38CrMoAl, with nitrified treatment. The traction frame adopts lifting type to make the best cooling effect no matter how wide the film is.
