Packaging and method of making packaging

Abstract

Packaging and a method of making the packaging is disclosed. The packaging includes a substrate with an asymmetrical coextrusion attached there to. The coextrusion includes an ethylene vinyl alcohol layer that is disposed toward the substrate.

1 . A packaging comprising:
 a substrate; and   an asymmetrical coextrusion attached to the substrate and including an ethylene vinyl alcohol layer that is disposed toward the substrate.   
     
     
         2 . The packaging of  claim 1 , further comprising a polymeric barrier layer applied to at least one side of the substrate and wherein the ethylene vinyl alcohol layer of the asymmetrical coextrusion is attached to the polymeric barrier layer. 
     
     
         3 . The packaging of  claim 2 , wherein the polymeric barrier layer is low density polyethylene. 
     
     
         4 . The packaging of  claim 2 , wherein the polymeric barrier layer includes at least one of low density polyethylene, medium density polyethylene, high density polyethylene, linear low-density polyethylene, and metallocene catalyzed linear low density polyethylene. 
     
     
         5 . The packaging of  claim 2 , wherein the polymeric barrier layer includes at least one of polypropylene, ethylene vinyl acetate resin, IONOMER, nylon, ethylene acrylic acid copolymer (EAA), ethylene methacrylic acid copolymer (EMAA), ethylene methyl acrylate copolymer (EMAC), and ethylene n-butyl acrylate copolymer (EnBA). 
     
     
         6 . The packaging of  claim 2 , wherein a surface of the polymeric barrier layer to which the ethylene vinyl alcohol layer is attached is treated to promote attachment of the ethylene vinyl alcohol layer to the polymeric barrier layer. 
     
     
         7 . The packaging of  claim 6 , wherein the treatment is flame treatment. 
     
     
         8 . The packaging of  claim 6 , wherein the treatment is corona treatment. 
     
     
         9 . The packaging of  claim 6 , wherein the treatment is a liquid primer. 
     
     
         10 . The packaging of  claim 1 , wherein the substrate comprises paper. 
     
     
         11 . The packaging of  claim 1 , wherein the substrate comprises a clear or metallized film selected from the group consisting of polyethylene terephthalate, oriented polypropylene (OPP), nylon, and polylactic acid (PLA) films. 
     
     
         12 . The packaging of  claim 1 , wherein the asymmetrical coextrusion further includes a tie resin and a sealant. 
     
     
         13 . The packaging of  claim 12 , wherein the tie resin and the sealant are blended together to form a tie sealant resin blend. 
     
     
         14 . The packaging of  claim 13 , wherein the asymmetrical coextrusion is a two layer coextrusion including the ethylene vinyl alcohol layer and a tie sealant resin blend layer. 
     
     
         15 . The packaging of  claim 14 , wherein the asymmetrical coextrusion is formable using a two resin capable coextruder. 
     
     
         16 . The packaging of  claim 12 , wherein the asymmetrical coextrusion includes the ethylene vinyl alcohol layer, a tie resin layer, and a sealant layer and wherein the tie resin layer is disposed between the ethylene vinyl alcohol layer and the sealant layer. 
     
     
         17 - 33 . (canceled). 
     
     
         34 . A packaging comprising:
 a substrate; and   an asymmetrical coextrusion attached to the substrate and including an ethylene vinyl alcohol layer and at least one support layer;   the ethylene vinyl alcohol layer is disposed toward the substrate and having a first face and a second face, wherein the first face directly contacts the at least one support layer and wherein the second face does not directly contact any other layer of the asymmetrical coextrusion.
