MT MULTI-LAYER CO-EXTRUSION (SMOOTH/ROUGH SURFACE) GEOMEMBRANE BLOWING MACHINE
Check the specifications
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 geomem-brane film solves this problem because of its rough surface.
The multiple coextrusion geomembrane blown film line manufactured by Jinming can achieve a maximum film width up to 8.5 film with a smooth surface, but also and 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.
Jinming 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.
