It is used for blowing high and low polyethylene, which has been widely used for producing laminating film,packing film,agricultural covering film, bag or film for 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 adopts 38 chrome-molybdenum aluminum which has been nitrogen treated and the traction frame adopts lifting type. No matter what size the film is ,it can achieve the best effect of cooling.
