Greenhouse Film Blowing Machine (3–5 Layers PE Film)
Co-extrusion blown film extrusion line for producing 6–22m wide greenhouse films with 4-6°C thermal insulation
Multi-layer extrusion system
Equipped with 2 to 5 extruders, melting and supplying materials for stable multi-layer film compounding
Large-diameter co-extrusion die head
Die diameter Φ1400 to Φ2600 mm, enabling precise compounding of 2 to 5 layers and supporting wide film widths
Internal cooling system
Internal cooling system ensures uniform temperature control and stable film properties
High-position haul-off system
Haul-off height 19,000 to 30,000 mm, speed up to 20 m/min, with 2,800 to 6,000 mm guide rollers for smooth traction and stable film flattening
Wide-width rewinding system
Designed for wide greenhouse films, supports tension adjustment, neat winding, and easier transportation and installation
Electrical control system
PLC touchscreen system with synchronized full-process control, supporting parameter setting, real-time monitoring, and alarm protection
- Wide-width forming capability
Supports greenhouse films up to 22 meters wide, reducing seams and joint leakage, improving sealing performance and structural reliability - Comprehensive multi-layer functionality
Capable of producing 2–5 layers PE film, offering better heat retention (4–6°C temperature increase), fast anti-fog performance (fog disperses within 30 seconds), strong UV resistance (service life 3 to 5 years), and suitability for various greenhouse environments - High cooling efficiency
Internal cooling improves cooling speed by about 20% compared to external cooling, ensuring thickness deviation <3% and a finished product qualification rate above 99% - Stable and reliable operation
Precision mechanical structure ensures stable high-load performance, with average continuous non-failure running time of around 1,200 hours - Broad application range
Supports film widths from 6 to 22 meters, suitable for small growers, medium farms, and large agricultural bases - Easy to operate
PLC and touchscreen interface provide intuitive control. Multiple production recipes can be stored, parameter switching is fast, and operators typically master operation within 1 to 2 days
