Abstract
Multilayer structures, methods of making the same and packages made therefrom are provided. The multilayer structures are useful for packaging bone-in meat or other like products. More specifically, the multilayer structures have sufficient rigidity and strength to contain bone-in meat or other like products. In addition, multilayer structures can easily seal to themselves or to other structures. Moreover, the multilayer structures are biaxially oriented and heat-shrinkable.

1-40. (canceled)
A method of packaging a bone-in meat product, comprising:
- obtaining a multilayer structure comprising:
- a first polyamide layer;
- a second polyamide layer;
- and
- a sealant layer;
- wherein the multilayer structure does not comprise a double wall or patch;
- and
- heat shrinking the multilayer structure around a bone-in meat product.
A method of packaging a bone-in meat product, comprising:
- obtaining a multilayer structure comprising:
- an outer layer comprising polyethylene;
- a first polyamide layer;
- a second polyamide layer;
- and
- a sealant layer;
- wherein the multilayer structure does not comprise a double wall or patch, and wherein the multilayer structure is biaxially oriented;
- and
- heat shrinking the multilayer structure around a bone-in meat product.
A method of packaging a bone-in meat product, comprising:
- obtaining a multilayer structure comprising:
- a first polyamide layer;
- a second polyamide layer;
- and
- a sealant layer;
- wherein the multilayer structure is biaxially oriented and does not comprise a double wall or patch, and wherein each of the first polyamide layer and the second polyamide layer comprises between 10% by volume and 60% by volume of the multilayer structure;
- and
- heat shrinking the multilayer structure around a bone-in meat product such that a bone of the bone-in meat product protrudes from the meat and contacts the multilayer structure.
A package comprising a multilayer structure and a bone-in meat product, the multilayer structure comprising:
- a first polyamide layer;
- a second polyamide layer;
- and
- a sealant layer;
- wherein the multilayer structure does not comprise a double wall or patch;
- and
- wherein the multilayer structure is heat shrunk around the bone-in meat product.
