Patent ID: 6872276

Claim:
A thin film lamination-delamination process comprising the steps of: a) providing a plastic support layer having first and second surfaces, said plastic support layer comprising a material selected from the group consisting of polyolefins, polyamides, polyesters, polyvinyl chloride, ethylene vinyl acetate, cyclo olefin polymers, and blends thereof; b) coextruding at least one thin plastic base layer, having first and second surfaces, onto at least one surface of said support layer, with the first surface of said at least one thin base layer in contact with a surface of said support layer, said thin plastic base layer having a thickness of from about 1 μm to about 10 μm and comprising a material selected from the group consisting of polyolefins, polyesters, polyamides, polyurethanes, polycarbonates, thermoplastic elastomers, high temperature polymers, and blends thereof; c) applying an adhesive layer onto the second surface of said base layer; d) attaching the base layer to a fabric via the adhesive layer whereby the adhesive bond strength between said base layer and said fabric is at least 3 times the interlayer bond strength between said base layer and said support layer; and e) separating the support layer from the base layer, such that the base layer remains attached to the fabric.
