摘要： This invention teaches using blends of polyisobutylene and polypropylene copolymer in the formation of single layer films and multiple layer sheet materials. The films and sheet materials are useful as flexible packaging materials. The multiple layer sheet materials may be entirely polymeric or may include layers having non-polymeric components, such as metal. The blends of polyisobutylene and polypropylene copolymer unexpectedly have the capability of being extruded through a slot die to form a film having a functionally useful mixture of its components. Thus the invention further includes methods of forming film-like layers of the blends of polyisobutylene and polypropylene copolymer.

摘要： 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.

摘要： Compositions of matter, sheet material, and packages made therefrom. Novel compositions of polypropylene and high density polyethylene are useful as sealant materials for flexible sheet material structures wherein the sheet material is sealable to a preformed container, to form a lid therefor, and is peelable therefrom, with cohesive failure of the sealant layer in the area of the formed seal. The novel sealant layer compositions provided for package closure and sealing which is capable of withstanding retort conditions while maintaining the integrity of the package closure and seal. Concurrently the lid is readily peeled from the package to provide access to the interior of the package. The peelability comprises cohesive failure of the sealant material in a novel blend of a polypropylene polymer with an ethylene polymer having a density of at least 0.940. The novel sealant materials of the invention can be used on a variety of multiple layer sheet material substructures, and particularly those providing barrier properties to food type packaging: especially barrier to the transmission of oxygen and moisture. Typical barrier materials are metal foil, vinylidene chloride copolymer, vinyl alcohol copolymer, olefin polymers and copolymers, and combinations of the above materials.

摘要： This invention pertains to the use of polymer blends in making multiple layer films. In some layers, the elastomer or ethylene-based copolymer is blended with polypropylene, and in some layers, with polyethylene. Typical films have two to five layers. In multilayer films, at least one layer of a blend of polyethylene, preferably high density polyethylene, with elastomer and/or ethylene-based copolymers. Another layer is polypropylene blended with elastomers and/or ethylene-based copolymers. The films may have as few as two layers, one each having polypropylene and polyethylene, preferably high density polyethylene. Additional layers may be added to the two or three layer films taught herein, for variety of purposes.
