Geomembrane Blowing Machine (6–8m Wide Width)
Geomembrane Production
Blown film extrusion line for producing 0.3-2mm high-strength construction films and geomembrane liners
This blown film extrusion line is designed for producing wide-width waterproof geomembranes and construction protection films. It is mainly used for manufacturing three-layer composite geomembranes and waterproof liners, and with optional auxiliary equipment, it can also produce textured geomembranes, achieving true multi-function capability with one machine.
The plastic film making line is equipped with a dedicated extrusion system, three-layer co-extrusion die head, and advanced cooling technology. The produced geomembranes feature excellent impermeability (permeability coefficient ≤ 10⁻¹¹ cm/s) and high tensile strength (≥ 18 MPa), providing strong durability and structural reliability. It can also be adapted for certain large-width agricultural greenhouse film production needs. The geomembranes and construction film blowing machine is widely used in several industries such as agricultural irrigation, aquaculture, water conservancy engineering, transportation and infrastructure projects, landfill and environmental protection projects, tailing pond waterproofing and industrial containment. It delivers stable, high-quality wide-width geomembrane solutions for demanding waterproofing and environmental protection applications.

Three special-design screws with three-layer spiral co-extrusion die head that ensures precise compounding of three molten layers
High-efficiency cooling system
IBC internal cooling combined with dual air-ring system for faster and more uniform cooling
Wide-width haul-off system
High-position haul-off structure (21,000–23,000 mm) to support stable traction and wide film forming
Rewinding and textured film module
Standard rewinder for conventional smooth films; with auxiliary equipment, textured geomembrane production can also be achieved
- High versatility and strong efficiency
Supports the production of waterproof geomembranes, textured geomembranes, and can also be adapted for greenhouse film production, increasing equipment utilization by about 50%. With a maximum output of 1500 kg/h, it meets large-scale industrial production demands. - Excellent product performance
Wide-width films of 6 to 8 meters help reduce leakage risk and improve construction efficiency. The finished geomembrane delivers impermeability ≤ 10⁻¹¹ cm/s, tensile strength ≥ 18 MPa, and a service life of over 10 years, while textured geomembranes provide 25% higher friction performance. - Stable and precise production
Non-stop screen changing takes only 3–5 minutes, with a product qualification rate of ≥99.5%. The combination of IBC internal cooling and dual air-ring technology ensures thickness tolerance within ±5%, meeting national standards. - Easy operation with reliable quality assurance
Touchscreen control enables fast parameter adjustment and troubleshooting. High-quality core components ensure stable long-term operation, with average non-failure running time exceeding 1500 hours, supporting a wide range of waterproofing and environmental protection projects.
