Abstract: Novel films, and processes for making them, are provided. The films are characterized by the inclusion of a layer of vinylidene chloride copolymer between at least two other layers which contain ethylene vinyl acetate, and optionally linear low density polyethylene. The films may be unoriented or oriented. Oriented films may optionally be cross-linked. The novel process of making the cross-linked films includes the step of cross-linking the film after assembly of the vinylidene chloride copolymer layer into the structure.

Abstract: Molecularly oriented films, and compositions used therein, comprise blends of a first EVA copolymer having a relatively low VA content, and a second EVA copolymer having a relatively high VA content. The blend exhibits a balance of properties which permit ready processability for orientation, while affording high levels of strength, particularly at elevated temperatures. Consequently laminates may be produced which are well suited for shrink packaging of meat, especially when a high oxygen barrier resin provides one layer thereof.

Abstract: An article is packaged in a multilayer flexible plastic sheet having a layer of a self-adhering plastic material and a layer of normally solid, thermoplastic organic polymer by (1) inserting the article between two opposing portions of the multilayer plastic sheet such that the layer of self-adhering plastic material faces the article; (2) collapsing the opposing portions into conforming contact with the article such that essentially all gases are permitted to pass out of the resulting package; and (3) sealing together the opposing contacting surfaces of said opposing portions to form a hermetically sealed package such that the self-adhering plastic material remains in clinging, conforming contact with the article and itself upon puncture of the multilayer plastic sheet.
