Abstract: The present invention is directed to a heat shrinkable film for packaging high gassing cheeses, specifically Swiss-type cheeses. The film includes at least one barrier layer of a copolyamide having a melting temperature of less than about 150° C., preferably nylon 6/6.9, and exhibits a CO2:O2 transmission ratio of at least 7.0 at 50% relative humidity. Furthermore, the film has a hot tensile strength at 85° C. of at least 1800 psi in at least one direction as measured by D882 and a percent elongation at 85° C. of at least 120% in at least one direction as measured by ASTM D882. Preferably, at least 50 percent by weight of the film is one or more ethylene copolymers, preferably one or more ethylene/vinyl acetate copolymers.
