1.Use:
1. - The double head film blowing machine is scientifically designed,With two die head but one extruder (one screw and cylinder)
With two die head, the machine can save cost and bring some ecomomical results.
2. - For producing two rolls of plastic film at once
3. - Available for both HDPE and LDPE
4.- This kind of machine has the advantage of higher production capacity, saving energy, labor cost and factory space.

3. Feature:
1. The full set machine is made of two sets 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 ate 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 head is plated with hard chrome of screw mandrel type structure with even and smooth discharging, the blown plastic film has fine finishing the blower is of labyrinth structure with even air output.
4. The coiling unit adopts pressure friction rewinding or center rewinding,which is driven by torque motor , with even and smooth rewinding and easy roll changing.
