Barrier & Coating Films

Barrier and coating films are polymer layers applied to liners to control resin flow and protect the liner during installation and curing. Materials such as polyurethane, polyethylene, polypropylene, and specialty barrier films help prevent resin leakage while improving chemical resistance and installation quality in liner manufacturing systems. Films are available in custom thicknesses, widths, and roll lengths, allowing integration into different liner production processes and resin systems.
