Performance The film blowing machine 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 improve 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 treated and the traction frame adopts lifting type. No matter what size of the film is , big or small, The film blowing machine can achieve the best effect of cooling double-cutting and Double-rolling; The film blowing machine adopts three torque motors , which can keep appropriate tension to make rolling even and coil changing easily. Rotary machine head: it can make the thickness of film and rolling surface smoother and more even , and The film blowing machine specially suitable for producing laminating film and printing film.
