USE:
It is used for blowing the plastic laminated film of low density polyethylene (LDPE), high density polythylene(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.It is used for blowing the plastic laminated film of low density polyethylene (LDPE), high density polythylene(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.
