It is used for blowing high-low pressure polyethylene, which has been widely used for producing laminating film, packing film, agricultural covering film bag or film textile and clothing and other packing material. The main motor adopts frequency control of motor speed to imrove the speed regulating stability of main motor and save electricity by 30%, The screw and material barrel adopt 38 chrome-molybdenum aluminum which has been nitrogen reated and the traction frame adopts lifting type. No matter what size the film is, big or small, it can achieve the best effect of cooling, Double-cutting and Double-rolling. It adopts three torque motors, which can keep appropriate tension to make rolling even and coil chan-ging easy. Rotary Machine Head: It can make the thickness of film even and rolling surface smoother and more even and it is specially sutable for producing laminating film and printing film.
