Abstract
Multilayer structures useful for packaging bone-in meat or other like products are provided. More specifically, multilayer structures are provided that have sufficient rigidity, strength, tear resistance and puncture resistance to contain bone-in meat or other like products. In addition, multilayer structures are provided for packaging bone-in meat and other like products that can easily seal to itself or to other structures to provide the packages for the products. Moreover, the multilayer structures of the present invention may be biaxially oriented and heat-shrinkable.
Claims44
A multilayer structure for packaging bone-in meat comprising:
- a heat-sealant layer comprising a material selected from the group consisting of polyolefins, ionomers, and blends thereof;
- a first polyamide layer;
- and
- a first tie layer,
- wherein all layers are coextruded together to form said multilayer structure and further wherein said multilayer structure is oriented.
