Eco-carton

Abstract

The Eco-Carton is constructed of a paperboard core with an outside mineralized barrier coating and with an inside aluminum film moisture barrier covered with an inside mineralized barrier coating to prevent the liquid from contacting the aluminum layer. The reduction of low density polyethylene plastic film from the composition of the Eco-Carton provides better recyclability of the used product.

What I claim as my invention is: 
     
         1 . A carton for holding liquids comprising:
 a paper board core layer,   an outside mineralized barrier coating,   an inside moisture barrier, and   an inside mineralized barrier coating,   said inside moisture barrier being positioned between said paperboard core layer and said inside mineralized barrier coating.   
     
     
         2 . The carton for holding liquids as claimed in  claim 1 , wherein a first mineralized adhesive layer is positioned between said paperboard core layer and said inside moisture barrier. 
     
     
         3 . The carton for holding liquids as claimed in  claim 1 , wherein a second mineralized adhesive layer is positioned between said inside moisture barrier and said inside mineralized barrier coating. 
     
     
         4 . The carton for holding liquids as claimed in  claim 1 , wherein said inside moisture barrier comprises an aluminum film. 
     
     
         5 . The carton for holding liquids as claimed in  claim 1 , wherein said outside mineralized barrier coating comprises a first flexible film composite, said first flexible film composite comprising a least one mineral material selected from the group consisting of ground calcium carbonate, diatomaceous earth, mica, silica, glass, zeolyte, and slate. 
     
     
         6 . The carton for holding liquids as claimed in  claim 1 , wherein said inside mineralized barrier coating comprises a second flexible film composite, said second flexible film composite comprising a least one mineral material selected from the group consisting of ground calcium carbonate, diatomaceous earth, mica, silica, glass, zeolyte, and slate. 
     
     
         7 . The carton for holding liquids as claimed in  claim 2 , wherein said first mineralized adhesive layer comprises a heat sealable layer of a first flexible film composite including at least one mineral-containing layer and containing a thermoplastic bonding agent. 
     
     
         8 . The carton for holding liquids as claimed in  claim 3 , wherein said second mineralized adhesive layer comprises a heat sealable layer of a second flexible film composite including at least one mineral-containing layer and a thermoplastic bonding agent. 
     
     
         9 . The carton for holding liquids as claimed in  claim 1 , wherein said carton comprises a gable top carton. 
     
     
         10 . A carton for holding liquids comprising:
 a paper board core layer,   an outside mineralized barrier coating,
 said outside mineralized barrier coating comprising a first flexible film composite, said first flexible film composite comprising a least one mineral material selected from the group consisting of ground calcium carbonate, diatomaceous earth, mica, silica, glass, zeolyte, and slate, 
   a first mineralized adhesive layer,
 said first mineralized adhesive layer comprising a heat sealable layer of a second flexible film composite including at least one mineral-containing layer and containing a thermoplastic bonding agent, 
   an inside moisture barrier,
 said inside moisture barrier comprising an aluminum film, 
   a second mineralized adhesive layer,
 said second mineralized adhesive layer comprising a heat sealable layer of a third flexible film composite including at least one mineral-containing layer and a thermoplastic bonding agent, and 
   an inside mineralized barrier coating,
 said inside mineralized barrier coating comprising a fourth flexible film composite, said second flexible film composite comprising a least one mineral material selected from the group consisting of ground calcium carbonate, diatomaceous earth, mica, silica, glass, zeolyte, and slate, 
   said inside moisture barrier being positioned between said paperboard core layer and said inside mineralized barrier coating,   said first mineralized adhesive layer being positioned between said paperboard core layer and said inside moisture barrier,   said second mineralized adhesive layer being positioned between said inside moisture barrier and said inside mineralized barrier coating.   
     
     
         11 . The carton for holding liquids as claimed in  claim 10 , wherein said carton comprises a gable top carton.
