Co-Extrusion Blown Film Machine (1-3 Layers PE/PP Films)
Packaging Film Production
Blown film extrusion line used to produce PE/PP films for shopping bags, garbage bags and plastic packaging bags
The co-extrusion blown film machine is engineered for modern packaging applications and is available in single-layer, double-layer, and three-layer configurations. Using polyethylene (PE, HDPE, MLDPE, LDPE, LLDPE) and polypropylene (PP) as primary raw materials, the blown film line employs advanced extrusion technology to efficiently produce a wide range of packaging films.
Typical end products include:
- Carrier bags (shopping bags, gift bags, etc.)
- Garbage bags (for household, commercial, and industrial use)
- Packaging bags (for food, daily-use products, apparel, etc.)
The co-extrusion line integrates advanced drive systems and optimized heating technology, reducing overall energy consumption by approximately 15-20%. With an integrated, end-to-end design covering the entire process from raw material feeding to finished product output, the system supports fully automated operation and accommodates diverse requirements for film thickness, width, and functional performance. It provides reliable, high-efficiency packaging solutions for food, retail, household, and industrial applications.
