摘要：
Polyolefin films having improved impermeability to gases and vapors, are coated on one or both sides with a layer of a copolymer containing hydroxyl, carboxyl and, optionally, ester groups, which has been obtained by hydrolysis of copolymers consisting of an unsaturated ester and of an unsaturated acid or a corresponding anhydride.
