Features
1. Two-layer co-extruded composite film can extend the shelf life of liquid packaging.
2. The barrel and screw of the extruder are made of high-quality alloy steel, which are precision-processed and nitrided to achieve the best hardness and durability.
3. The auxiliary machine is equipped with a platform workbench to facilitate operation and prepare bubble rings.
4. Winding device: double-winding and double-cutting, its power adopts torque motor, which can maintain appropriate tension, neat winding and convenient roll change.
Application
Used for blowing plastic composite films such as low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). Widely used in express bags, liquid packaging, printing substrates, export product packaging, industrial product packaging, etc.
