Abstract:
A multilayer heat-shrinkable film comprising:a first outer layer formed from a resin composition having a Vicat softening point of at least 100Â° C.; a second outer layer including one or more thermoplastic gloss materials selected from the group consisting of polyester, ethylene/alpha-olefin copolymer having a melt index of greater than 1 g/10 minutes, styrene/butadiene block copolymer, and ethylene/styrene random copolymer; and one or more inner layers between the first and second outer layers, at least one of the inner layers including an ethylene/&agr;-olefin copolymer, wherein: the multilayer film has a total free shrink of at least 40% at 85Â° C.; and if the second outer layer includes a given amount by weight of polyester, then: i) each of the inner layers of the multilayer film is devoid of an amount by weight of polyamide greater than the given amount by weight of polyester in the second outer layer and ii) each of the inner layers of the multilayer film is devoid of an amount by weight of polyester greater than the given amount by weight of polyester in the second outer layer.
