Easy-Open Cook-In Packaged Product

A packaged product comprising an easy-open packaging article including a multilayer film surrounding and adhering to a cooked meat product, with the packaging article having a heat seal of the inside surface of the film to itself, the multilayer film comprising:

• (A) a first layer that is an inside seal layer comprising a thermoplastic polymer comprising at least one member selected from the group consisting of (i) ionomer resin that bonds to ethylene homopolymer with a bond strength of less than 36 grams per inch, (ii) polyamide, and (iii) polyester;
• (B) a second layer that bonds to the first layer with a bond strength of at least 36 grains per inch;
• (C) wherein the second layer, or a third layer with the second layer being between the first layer and the third layer, comprises a tear-enhancing component comprising at least one member selected from the group consisting of an inorganic filler and an incompatible polymer blend, wherein:
• the filler is present in an amount of at least 5 weight percent, based on layer weight, and the filler comprises at least one member selected from the group consisting of silicate, silica, siloxane, silicone resin, zinc sulfide, wollastonite, microspheres, glass fiber, metal oxide, calcium carbonate, sulfate, aluminum trihydrate, feldspar, perlite, gypsum, iron, fluoropolymer, crosslinked polymethylmethacrylate, talc, diatomaceous earth, zeolite, mica, kaolin, carbon black, and graphite, and the second or third layer containing the filler makes up at least 10 weight percent of the film, based on total film weight;
• and
• the incompatible polymer blend comprises at least one member selected from the group consisting of:
• (i) a blend of from 90 to 30 weight percent ethylene homopolymer and/or ethylene/alpha-olefin copolymer with from 10 to 70 weight percent ethylene/unsaturated ester copolymer having an unsaturated ester content of at least 10 weight percent;
• (ii) a blend of ionomer resin with ethylene/unsaturated ester copolymer, and/or polybutylene, and/or propylene homopolymer and/or propylene copolymer;
• (iii) a blend of homogeneous ethylene/alpha-olefin copolymer with recycled polymer blend comprising ethylene homopolymer, propylene homopolymer, ethylene copolymer, propylene copolymer, polyamide, ethylene/vinyl alcohol copolymer, ionomer resin, anhydride-modified ethylene/alpha-olefin copolymer, and/or antiblock;
• (iv) a blend of from 10 to 75 weight percent ethylene/unsaturated ester copolymer with from 90 to 15 weight percent polypropylene and/or propylene/ethylene copolymer, and/or polybutylene, and/or modified ethylene/alpha-olefin copolymer, and/or styrene homopolymer, and/or styrene/butadiene copolymer;
• (v) a blend of ethylene/norbornene copolymer with ethylene/unsaturated ester copolymer and/or polypropylene and/or polybutylene;
• (vi) a blend of from 90 to 15 weight percent ethylene/alpha-olefin copolymer with from 10 to 75 weight percent polypropylene and/or polybutylene and/or ethylene/norbornene;
• (vii) a blend of from 90 to 25 weight percent homogeneous propylene homopolymer and/or homogeneous propylene copolymer with from 10 to 75 weight percent homogeneous ethylene/alpha-olefin copolymer and/or ethylene/unsaturated ester copolymer;
• (viii) a blend of propylene homopolymer and/or propylene/ethylene copolymer and/or polybutylene with ethylene/methyl acrylate copolymer and/or ethylene/acrylic acid copolymer and/or ethylene/butyl acrylate copolymer;
• (ix) a blend of polyamide with polystyrene and/or ethylene/alpha-olefin copolymer and/or ethylene/vinyl acetate copolymer and/or styrene/butadiene copolymer;
• and
• (x) a blend of polyamide 6 and polyamide 6I6T;
• and the incompatible polymer blend is present in at least one layer of the multilayer film, and the incompatible polymer blend makes up at least 20 weight percent of the film, based on total film weight.
