A heat-shrinkable film containing a homogeneous ethylene/alpha-olefin copolymer has a high impact strength and a high free shrink. The film can be a monolayer film or multilayer film, with the homogeneous ethylene/alpha-olefin copolymer present alone or in a blend, and in one or more film layers. The film is especially suited for use in heat-shrinkable bags, which can be used for the packaging of various products, especially meat.

A multilayer film, which is particularly suited to packaging of cheese on a Hayssen RT packaging machine, has a first layer comprising cyclic olefin copolymer having a glass transition temperature of at least 125 C. , and a second layer comprising at least one member selected from the group consisting of cyclic olefin copolymer having a glass transition temperature of at least 125 C. , polyamide, polyester, and polystyrene. The first and second layers are on opposite sides of a tensile axis of symmetry of the film. The film exhibits from 0 to 45 degrees of transverse edge curl, a yield point of at least 1200 psi at a temperature of 85 C. , and an elongation at break of from 0 to 300 percent at 85 C. In addition, a packaging process comprises supplying the film and placing a plurality of product units on the flat film at desired intervals, forwarding the flat film having product units thereon, while forming a tubing from the flat film so that product is inside the tubing, followed by sealing the film along its length and transversely (upstream and downstream of the product), so that the product is a discrete packaged product is formed.

A film comprises first, second, and third layers. The first layer comprises vinylidene chloride polymer. The second layer comprises a dispersion of tie polymer and nanoparticles. The third layer comprises thermoplastic polymer. The second layer is between and directly adhered to both the first and third layers. The film provides an enhanced interlayer bond strength between the layers at the elevated temperatures associated with cook-in, retort, and/or pasteurization thermoprocessing.

Gas impermeable thermoplastic films of multilayer construction are disclosed which are particularly suitable for use in the manufacture of inflatable packaging cushions for protection of packaged objects. The multilayer films have outer heat sealable layers which are radio frequency inactive. The inflatable packaging cushion is fabricated by heat sealing the outer layers of the multilayer film together to form gas inflatable pockets using conventional heat sealing techniques. The heat sealed regions have increased mechanical strength without the need for post irradiation treatment. The thermoplastic film includes at least two outer layers of heat sealable material including linear low-density polyethylene polymers separated by a gas impermeable layer, e. g. , an oxygen barrier. Additional adhesive layers and/or structural intervening layers may be coextruded in forming the resulting thermoplastic films.
