A four layer meat-adherable cook-in shrink film comprising: (a) a first or meat adherable layer comprising an ionomer of a metal salt-neutralized copolymer of an olefin and a carboxylic acid; (b) a second or inner core layer directly adhered to one side of said first layer comprising a blend of between about 20 and 60 wt.% anhydride-modified ethylene copolymer adhesive having a Vicat softening point of at least about 194°F. and a melting point between said first layer and the hydrolyzed ethylene vinyl acetate copolymer of the third layer, and between about 40 and 80 wt.% ethylene vinyl acetate containing between about 9 and 15 wt.% vinyl acetate, said blend having a melt index up to and including about 0.9; (c) a third or barrier layer directly adhered to the opposite side of said second layer from said first layer and comprising a blend of between about 60 and 90 wt.% hydrolyzed ethylene vinyl acetate copolymer containing between about 28 and 40 wt.% ethylene, and between about 10 and 40 wt.% amide polymer having a melting point below about 420°F.; (d) a fourth or abuse layer directly adhered to the opposite side of said third layer from said second layer comprising a blend of between about 10 to 40 wt.% anhydride-modified ethylene copolymer adhesive having a Vicat softening point of at least about 194°F. and a melting point between said first layer and said hydrolyzed ethylene vinyl acetate copolymer of said third layer, and between about 60 and 90 wt.% ethylene vinyl acetate containing between about 9 and 15 wt.% vinyl acetate, said blend having a melt index up to and including about 0.9; and (e) the entire film being irradiated.
