Abstract

The multilayer film comprises a first outer layer which is heat sealable. The first outer layer comprises from 95 to 100 percent (by weight of the first outer layer) of a first polymer said first polymer being derived from propylene monomer and optionally one or more comonomers selected from the group consisting of ethylene and C4 C8 alpha olefins. The first polymer should have a melting point of at least 125C. The multilayer film further comprises an inner portion adjacent to the first outer layer. The inner portion may be a single layer or may comprise several layers. At least one layer of the inner portion comprises an elastomeric propylene based polymer ("EPBP"). Further at least one layer of the inner portion comprises a second polymer wherein the second polymer is selected from the group consisting of high pressure low density polyethylene high density polyethylene ethylene acrylic acid copolymers ethylene (meth) acrylic acid copolymers and combinations thereof. The second polymer may be together with the EPBP in the same layer or may be in a separate layer. It is also contemplated that the inner portion may optionally comprise one or more additional layers which may or may not contain EPBP or the second polymer. The multilayer film further comprises a second outer layer arranged so that the inner portion is encapsulated between the first outer layer and the second outer layer. The second outer layer comprises a third polymer wherein said third polymer is selected from the group consisting of homopolymer polypropylene random copolymer polypropylene and impact copolymer polypropylene and blends thereof.
