Product Description
SJ-60(70) single-screw double-die film blowing unit is used for blowing various low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) and other plastic films. Widely used in the packaging of food, clothing textiles, daily necessities and industrial products.
Performance and features
- The machine adopts single-screw extruder, double-feeling film out, equipped with double traction and double take-up devices, which has the characteristics of high output and low consumption.
- Both the screw and the barrel are made of 38CRMOALA alloy steel, which is made of nitriding treatment and precision machining, with high hardness, strong corrosion resistance and durability
- The die head is plated with hard chrome, and its structure is spiral mandrel type, the extruded molten material is uniform, and the blown film has a good finish; the structure of the air cooling device is a labyrinth, and the air volume is uniform.
- The coiling device adopts pressure friction winding or center winding, and is adjusted by torque motor, so that the winding is smooth and easy to change.
Optional equipment
1)Auto loader 2)corona treatment 3)air compressor 4)rotating die head 5)Fast type screen changer 6)double back to back winder 7)air shaft
