ABSTRACT:
An oxygen and moisture impermeable multilayer barrier film is provided including a barrier layer comprising a homopolymer of vinylidene chloride or a copolymer of vinylidene chloride and vinyl chloride or methyl methacrylate. The barrier layer may be coated onto or coextruded with a water soluble film layer comprising a blend of a water soluble polymer such as polyvinyl alcohol, polycaprolactone, or polyethyloxozaline and a thermoplastic polyurethane. The multilayer film may be used for reusable or disposable ostomy bags and for heat sealable bags used in packaging agricultural chemicals, detergents, and other household chemicals.
