Claim Text:
1. A package comprising a multilayer structure and a bone-in meat product, the multilayer structure comprising: an outer layer comprising polyethylene, wherein the volume percent of the outer layer is between 5% and 25% of the multilayer structure; a first polyamide layer, wherein said first polyamide layer comprises a blend of between 91% by weight and 99% by weight semi-crystalline polyamide and 1% by weight to 9% by weight amorphous polyamide, wherein the volume percent of the first polyamide layer is between 15% and 25% of the multilayer structure; a first tie layer disposed between and in contact with each of said outer layer and said first polyamide layer, wherein the volume percent of the first tie layer is between 2% and 15% of the multilayer structure; a barrier layer disposed in contact with said first polyamide layer wherein said barrier layer comprises ethylene vinyl alcohol copolymer having an ethylene content of between 27 mol % and 42 mol %; a second polyamide layer disposed in contact with said barrier layer, wherein said second polyamide layer comprises a blend of between 91% by weight and 99% by weight semi-crystalline polyamide, and between 1% by weight and 9% by weight amorphous polyamide, wherein the volume percent of the second polyamide layer is between 15% and 25% of the multilayer structure; a sealant layer, wherein the sealant layer comprises polyethylene, wherein the volume percent of the sealant is greater than the volume percent of the outer layer; and a second tie layer disposed between and in contact with each of said sealant layer and said second polyamide layer, wherein the volume percent of the second tie layer is between 2% and 15% of the multilayer structure, wherein the thickness of the multilayer structure is between 1.5 mils and 5 mils, wherein the multilayer structure is biaxially oriented, and the package comprises a bone-in meat product contained therein, where a bone of the bone-in meat product protrudes from the meat and contacts the multilayer structure, wherein the multilayer structure does not comprise a double wall or patch, is heat-shrinkable, annealed and has rigidity, strength, oxygen barrier and puncture resistance to hold the bone-in meat product.
