Laminated multiple layered thermoplastic film structure comprising a single layered extruded portion which is laminated to a coextruded sealant film structure containing a cheese release additive are disclosed. The film structures are useful in the packaging of food products, especially cheese.

Laminated thermoformable film structures useful for packaging food products

Non-wax film structures having three layers wherein the first skin layer comprises a polymer or blend of polymers and a hydrogenated aliphatic hydrocarbon additive; a second core layer comprises a polymer or a blend of polymers, a hydrogenated aliphatic hydrocarbon additive and regrind material; and a third sealant layer comprises a polymer or blend of polymers and a cheese release agent are disclosed. The film structures are useful in the packaging of food products, especially cheese.

Non-wax packaging film

Multilayer films and packaging structures having a delamination seal and an oxygen barrier layer are disclosed. The delamination structure adjacent to the EVOH oxygen barrier layer binds well to the EVOH layer and also retains its ability to delaminate. The multilayer films, and packages in which they are utilized, have several layers including a first, external layer; a second, tie layer comprising a mixture of polybutylene and an anhydride modified polyethylene such that a peelable bond is formed between said first, external layer and said second, tie layer; a third, core layer comprising ethylene vinyl alcohol which functions as an oxygen barrier layer; a fourth, tie layer comprising an anhydride modified polyethylene and a fifth, external layer.
