Geomembrane ( also called Pond Liner) :
The manufacturing of geomembranes begins with the production of raw materials, which include the polymer resin itself,  various  additives  such  as  antioxidants, plasticizers, fillers, carbon black, and lubricants.  These  raw  materials  are  then processed into geomembrane sheets of various widths and thickness by extrusion.
