RBMT Multiple-layer Coextrusion Geomembrane Blown Film Line

Geomembrane film is widely used in refuse landfill, roads and bridges projects, tunnels, green projects, sewage ponds, etc.


Because the surface of traditional geomembrane film is very smooth, its coefficient of friction is so low that it’s easy to slide on the ground, especially when it is used in a ramp project. Textured geomembrane film solves this problem because of its rough surface.


The multiple coextrusion geomembrane blown film line offered by ROLBATCH can achieve a maximum film width up to 8.5 meters. It not only produces geomembrane film with a smooth surface, but also an optional rough surface. The textured geomembrane film is produced in one-step coextrusion process with good chemical resistance capability, good environmental stress crack resistance, and low penetrability. White, black or other functional masterbatches can be applied according to customer’s request.


Our multiple-layer coextrusion textured geomembrane blown film line allows users to produce geomembrane film with rough surface on single-side or double-side. Additionally, the width of the smooth edge of the film can be adjusted for welding.
