Use:
It is used for blowing the plastic laminated film of low density  polyethylene (LDPE), high density polyethylene(HDPE)and linear low density  polyethylene(LLDPE) etc., Which are widely used for packing liquid, printed base  material, products for export and industrial products, etc.

Characteristics:
1. Double-layer co-extrusion laminated film can prolong the length for preservation of liquid package.
2. The cylinder and the screw stem of the extruder are made of high quality alloy steel with optimum hardness and durable service after precision finishing and nitrogen treatment.
3. The auxiliary machine has a platform working table for making operation easy and is equipped with bubble stabilizing ring.
4. Double-rolling and double-cutting coiling unit adopts torque motor to keep proper tensions and make rolling even and roll- changing easy.

Optional Equipment:
1) Auto Loader
2) Corona Treater
3) Die Rotary Device
4) Air Compressor
5) Mechanics Screen Changer
6) Auto Winder
