A multilayer film structure having at least two layers wherein the first layer comprises poly(ethylene) having a density range from about 0. 93 g/cc to 0. 97 g/cc; and a second layer comprising poly(ethylene) having a density range from 0. 89 g/cc to 0. 93 g/cc wherein the second layer is capable of forming a heat seal. The multilayer film structure is capable of being laminated to another film structure or a packaging film component. The packages of the present invention are useful for the packaging of flowable materials.

A multiple layer sheet material comprising a first layer 12 of vinylidene chloride copolymer having a first softening temperature. A second polymeric sealant layer 14 has a second softening temperature no more than about 50. degree. C. less than the first softening temperature. An optional third layer 16 between the first and second layers has a third softening temperature greater than either of the first and second softening temperatures and comprises a polyethylene terephthalate composition. A fourth polymeric layer 18 has a fourth softening temperature greater than the first and second softening temperatures. The first layer is positioned between the third and fourth layers. A fifth impact layer 20 is positioned between layers 14 and 16. The composition of the impact layer 20 comprises, as a first component, a base polymer drawn from the same family of polymers as a major polymeric component of the second sealant layer, and, as a second component, a polymeric composition providing elastomeric properties to the impact layer and increased shock tolerance to the multiple layer sheet material. The disclosure also teaches the use of the sheet materials in fabrication of packages and teaches methods of fabricating both the sheet materials and the packages.

Multi-layer films having an outer sealant layer which readily delaminates from the adjacent sealant layer are disclosed. For retort applications, preferably one of the outer or adjacent sealant layers is comprised of a majority of ethylene moieties and the other of the outer or adjacent sealant layers is comprised of a majority of propylene moieties. The film is especially well-suited for use as a lidstock sealed to a container, such as a tray.
