Geomembrane Production Site | Blown Film Extrusion Process

Geotechnical membranes are manufactured from high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) using advanced extrusion, cooling, shaping, and winding technologies. The product provides outstanding impermeability, aging resistance, and chemical durability, widely used in hydraulic projects, landfills, tunnels, anti-seepage ponds, and artificial lakes.

At present, the most mainstream and widely used process is blown film (also known as flat extrusion blow molding). Please watch the factory video
