The Three-layer Co-extruded Rotary Film Blowing Machine is designed for industrial-scale multilayer film production, enabling simultaneous extrusion of A/B/A or A/B/C structures in one continuous process.
This system integrates extrusion, rotary die head technology, film blowing, and PLC automation control into a stable production line for long-term continuous operation.
Why Choose This Machine?
Improved Film Uniformity with Controlled Thickness Accuracy
The 360° rotary die head ensures stable bubble formation and controls film thickness deviation within ±5%, improving final film consistency for high-end packaging applications.
Energy Saving Production
The machine adopts high-efficiency heating systems and frequency inverter control, reducing energy consumption by approximately 15%–20% compared with conventional film blowing machines, helping reduce long-term operating cost.
Flexible Three-Layer Co-Extrusion Structure
Supports multiple film structures including:
- A/B/A structure for cost-sensitive packaging
- A/B/C structure for functional barrier film
- Virgin + recycled material blending
- Each extrusion layer is independently controlled for precise material ratio adjustment.
Stable Industrial Output Capacity
Depending on configuration:
- Output capacity: 80–120 kg/h
- Screw speed: 15–150 r/min
Wide Material Compatibility
Compatible materials include:
- HDPE
- LDPE
- LLDPE
- PA (optional multilayer structure)
- Recycled polyethylene materials
