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.

Multiple layer polymeric films and process for making them

Ethylene vinyl alcohol copolymer is blended with polyetheramide block copolymer to form a novel composition of matter. The blended composition can be extruded and/or coextruded to make packaging films. In the most preferred embodiments, the blend is contained as one layer in a film comprising a multiplicity of layers, and at least the blend layer is molecularly oriented. Methods of making the films are also disclosed.

Process for making multiple layer polymeric films

A novel composition of matter having surprising physical properties when fabricated into multiple layer films is disclosed. The composition is generally a blend of nylon 6 with a nylon copolymer comprised of nylon 6 and a second nylon polymer. The second nylon polymer is 2.5 to 10 mole percent of the overall composition. The remaining 97.5% to 90% of the composition is the nylon 6 and the nylon 6 component of the copolymer. The nylon composition may be comprised entirely of a nylon copolymer having 90% to 97.5% nylon 6 and 10% to 2.5% of a second nylon polymer. The multiple layer films fabricated with the nylon compositions show unexpected range of thermoforming and heat sealing capabilities and good heat resistance, similar to that of nylon 6.
