Standup Pouch With Multiple Plies

Abstract

The standup pouch includes a front a back and a gusseted region. The front and back are joined together at a the opposing side edges by way of opposing side seals. The gusseted region includes a first gusset panel and a second gusset panel that are coupled together at an inner end at a gusset fold and extending outwardly to of the first and second lower folds. The gusseted region including a first gusset seal area joining the first gusset panel to the front, and a second gusset seal area joining the second gusset panel to the back. The first and second gusset seal areas are coupled together and to the opposing side seals so as to form a substantially fluid tight cavity therebetween. The standup pouch formed from a first ply and a second ply which are joined together at the side seals and the gusset seals.

         7 . The standup pouch of  claim 6  wherein the multilayer extrusion further includes a tie layer between the central layer and the PE layer on either side of the central layer. 
     
     
         8 . The standup pouch of  claim 2  wherein the outer layer comprises PET and the central layer comprise a cavitated OPP. 
     
     
         9 . The standup pouch of  claim 8  wherein the inner layer comprises a PE. 
     
     
         10 . The standup pouch of  claim 9  wherein the inner layer comprises a multilayer coextrusion. 
     
     
         11 . The standup pouch of  claim 10  wherein the multilayer extrusion comprises a central layer of nylon having a PE layer on either side thereof. 
     
     
         12 . The standup pouch of  claim 11  wherein the multilayer extrusion further includes a tie layer between the central layer and the PE layer on either side of the central layer. 
     
     
         13 . A standup pouch comprising:
 a front having a top edge, a first lower fold and opposing side edges, a back having a top edge, a second lower fold and opposing side edges, the front and back joined together at a the opposing side edges by way of opposing side seals;   a gusseted region including a first gusset panel and a second gusset panel, the gusset panels coupled together at an inner end at a gusset fold and extending outwardly to a respective one of the first and second lower folds, the gusseted region including a first gusset seal area joining the first gusset panel to the front, and a second gusset seal area joining the second gusset panel to the back, the first and second gusset seal areas being coupled together and to the opposing side seals so as to form a substantially fluid tight cavity therebetween; and   a zipper element assembly spaced apart from the top edge and including a first zipper element assembly on an inside surface of the front and a second zipper element assembly on an inside surface of the back, the zipper element configured to selectively facilitate access to the cavity;   the standup pouch formed from a first ply and a second ply which are joined together at the side seals, the gusset seals and the zipper element assembly.   
     
     
         14 . The standup pouch of  claim 13  further including a seal extending across the top edge so as to seal the front to the back proximate the top edge. 
     
     
         15 . The standup pouch of  claim 14  wherein the first gusseted area is coupled to the second gusseted area at each side edge, in a position spaced apart from the gusset fold and the first and second lower folds. 
     
     
         16 . The standup pouch of  claim 15  further including at least one rip indent positioned at one of the opposing side edges between the zipper element assembly and the top edge.
