A multilayer thermoplastic film, and packages made from the film, comprising a layer of ethylene vinyl alcohol (EVOH) as an oxygen barrier layer, a layer of a polymer or copolymer formed by the polymerization reaction with a single site catalyst and ethylene vinyl acetate (EVA) as a sealant layer, and alternatively containing a layer of EVA, said film having improved sealability and improved clarity as compared to conventional films.

Multi-layer thermoplastic films and packages made therefrom

A multi-layer packaging film comprising layers having varying degrees of cross-linking when subjected to electron beam (EB) radiation. The outer layer has a high degree of cross-linking to improve the adhesion, strength, toughness and heat resistance of the film and the inner layer has a low degree of cross-linking to improve the sealability. Bags made from the multiple layer films are especially useful for shrink packaging, and particularly for shrink packaging of meats having large cavities.

Heat shrinkable film structures with improved sealability and toughness

Copolymers of ethylene and alpha olefins that have been formed by the polymerization reaction in the presence of a single site catalyst, such as a metallocene, are used to form collapsible dispensing containers and/or components thereof. Blends of the copolymers with propylene polymers are disclosed and used to form a body wall layer or a collapsible dispensing container head having good bond strength with a body wall layer formed of an ethylene polymer. Methods for improving the adhesion between collapsible dispensing container components, such as between body wall layer formed of an ethylene polymer and another body wall layer formed of a propylene polymer, or between a body wall layer formed of an ethylene polymer and a collapsible dispensing container head formed of a propylene polymer, are also disclosed.

Structures of polymers made from single site catalysts

Films comprising a first layer, composition of said first layer comprising a blend of an ethylene vinyl acetate copolymer; linear low density polyethylene; a second ethylene vinyl acetate copolymer; and slip; a second layer, composition of said second layer comprising ethylene vinyl acetate copolymer and wherein each first and second layer having two surfaces; a third layer, composition of said third layer comprising vinylidene chloride methyl acrylate and wherein said third layer is disposed between said first and second layer; a fourth layer, composition of said fourth layer being the same as said first layer wherein said fourth layer is adhered to said first layer on the surface opposite said third layer; and a fifth layer, composition of said fifth layer comprising a blend of linear low density polyethylene and low density polyethylene wherein said fifth layer is adhered to said second layer on the surface opposite said third layer are provided for.

Heat shrinkable barrier bags

A multiple layer polymeric film having five layers and wherein an antiblock additive and an slip additive may optionally and independently be present in layers 1, 2, 4 and 5 and wherein said antiblock additive may be a blend of two or more antiblock additives and wherein both of said slip additive and said antiblock additives are present at about 0.1%-10%, based on the total weight of the layer.

Heat shrinkable barrier bags with anti block additives

A three layer heat shrinkable film is disclosed, along with preferred process for making it. The film comprises a first heat sealable layer of an ionomer, a second layer of a vinylidene chloride copolymer, and a third layer of a blend of an ionomer and an EVA copolymer. The EVA content is no greater than 20% of the blend by weight, and the vinyl acetate content is at least 4.5% of the blend by weight. In the preferred process, a three layer tape is coextruded and cooled, and reheated to 197.degree.-203.degree. F., and oriented in a conventional double bubble process.
