Product Description
  • Product Description
    This two-colour film blowing machine is designed to produce supermarket bags, T-shirt bags, shopping bags, and other film products such as tablecloths. The A+B extruder can manufacture single-layer films in different colours, or double-layer films—one layer made from recycled material and the other from virgin material—helping to reduce production costs.
  • Film Quality
    High-quality film with a smooth surface and excellent toughness. High production efficiency helps improve throughput and reduce overall production costs.
  • Advantage
    The service life of the screw can reach 3–5 times that of ordinary screws. The winder uses an inverter motor to maintain proper tension, ensuring the winding is neat and the roll can be changed easily. Most importantly, the winder can achieve automatic roll discharge. To a certain extent, the machine helps save raw materials and reduce internal friction, while also saving labour—making it a popular choice with customers.
