Abstract:
A release liner web has thermoplastic membranes coated on opposite sides of the release liner web that are thermoplastically fused proximally to an edge of the release liner web, nearly doubling the width of thermoplastic membranes that can be prepared using conventional equipment. Also described are geomembranes prepared from an amorphous or semi-crystalline thermoplastic sheet material and having a high gloss surface, and methods of manufacture and use of same.
