This unit uses LLDPE as main material and adopts several kinds of resins to manufacture the double-side self-sticky stretch wrapping film. The film has good tensile strength, anti-pricking ability and impact strength. Its good shrinking memory function and self-sticky can make goods integrity to prevent goods from loosening and collapsing during transportation and being polluted by dust. 

1) Screw item and cylinder are all made of 38CRMOALA alloy and treated by nitrogen.
    It has an advantage of corrosion resistance and endurance
2) Cooling water system is to provide the best transparent effect, which will increase
    the production of the extruder
3) Take-up equipment adopts with friction type rewinding and equipped with edge  correcting device to ensure the quality.
