Double Color Film Blowing Machine

1.blow different kinds of striped vest bags(shopping bag) 2.material: HDPE,LDPE.

CHARACTERISTICS

The two-color striped film blowing machine Set is composed with two screw stems and cylinder with one die head, it adopts the device of two different plastic materials, which can blow different kinds of striped vest bags(shopping bag), it can get colorful bags without printing, with such features as beautiful colors, average stripes, logical structure, advanced technology, even rewinding and high output.

Characteristics

1.The full machine set is made of one set main motors, two cylinders and one layer die head, feeding by two cylinders. Extruding with one die head one traction and rewinding device, it can improve the quality of striped film by adopting with one traction and one rewinding device.2.The screw stem and cylinder are made of 38CrMoAl high quality alloy steel after fine finishing and nitrogen treatment, which has high hardness, strong resistance to corrosion, durable service. 3.The die head is plated with hard chrome, of screw mandrel type structure with more uniform and smooth discharging, the blown plastic film has fine finishing, the blower with labyrinth structure has more uniform air output. 4. The coiling unit adopts pressure friction rewinding or center rewinding, which is driven by torque motor, with more uniform and smooth rewinding and easy roll changing.
