Multi-layered ionomer-vinylidene chloride contact laminated structures

摘要

A laminated structure comprises an ionomer polyethylene carboxylate-containing film secured to a second film through a vinylidene chloride copolymer adhesive wherein the vinylidene chloride copolymer includes on a comonomer weight basis: (a) from about 45 to about 90 percent vinylidene chloride, (b) from about 5 to about 25 percent of a polar comonomer having one or more hydroxyl groups, and (c) from about 0 to about 30 percent of a plasticizing monomer for vinylidene chloride in combination with: (d) a cross-linking agent dissolved in the continuous aqueous phase of the vinylidene chloride copolymer.
