It is suitable for blowing the plastic film as high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE), which is widely used for packing foodstuff, garment, textile, daily-used articles and industrial production etc. I can also produce pearl film or degradation film by adopting special raw materials Highlights: 1) Its Die head could rotate within 360 degree angles, which could strength the indensity and evenness of plastic film. 2) The screw and cylinder are made of 38CrMoAl high quality alloy steel after fine finishing and nitrided treatment, which has high hardness, strong resistance to corrosion,durable service. 3) The die is plated with hard chrome, of screw mandrel type structure with even and smooth discharging, the blown film has fine finishing. The blower is of labyrinth structure with even air output. The take-up unit adopts lifting type of square-frame platform structure, the height of lifting frame can be adjusted automatically according to different technologicalrequirement. 4) The re-winding unit adopts pressure friction rewinding, which is durven by torque motor, with even and smooth rewinding and easy roll changing
