ENCAPSULATED BARRIER FOR FLEXIBLE FILMS AND A METHOD OF MAKING THE SAME

摘要

Coextruted films having a heat a sensitive barrier layer (110) comprising materials such as EVOH, nylon etc, which has been encapsulated by a first adhesive material (112), and additional adhesive layers of a higher melting polymer (113) deposited on the first adhesive layer. The first adhesive layers help to protect the heat sensitive barrier material from the heat of extrusion/lamination.
