Tobacco pouch product

Abstract

A pouched tobacco product includes a lined pouch material of a web and a water-soluble liner adjacent the web and a tobacco component contained within the lined pouch material. The water-soluble liner is interposed between the web and the tobacco component. The liner preferably reduces staining of the web by the tobacco component. Additionally, the liner may include a flavorant.

What is claimed is: 
     
         1 . A lined pouch material of a pouched tobacco product, comprising:
 a saliva-permeable water-insoluble web; and   a discrete separately-formed water-soluble film or layer of liner adjacent the web;   wherein the film or layer optionally comprises a water-soluble flavorant.   
     
     
         2 . The lined pouch material of a tobacco product according to  claim 1 , wherein the web has a basis weight of about 5-25 g/m 2 , and/or a wet tensile cross-direction (CD) strength of about 15-75 N/m. 
     
     
         3 . The lined pouch material of a tobacco product according to  claim 1 , wherein the lined pouch material comprises longitudinal edge portions essentially free of liner, such that a longitudinal seam of a pouched tobacco product essentially free of liner may be formed when folded into a tubular form of the lined pouch material. 
     
     
         4 . The lined pouch material of a tobacco product according to  claim 3 , wherein the lined pouch material comprises spaced apart discrete regions of liner, such that longitudinal and transverse seams of a pouched product essentially free of liner may be formed from the lined pouch material. 
     
     
         5 . The lined pouch material of a tobacco product according to  claim 1 , wherein said web and liner are laminated. 
     
     
         6 . A lined pouch material of a pouched tobacco product, comprising:
 a web; and   a film or layer of liner adjacent the web;   wherein the film or layer optionally comprises a water-soluble flavorant.   
     
     
         7 . The lined pouch material of a tobacco product according to  claim 6 , wherein the web has a basis weight of about 5-25 g/m 2 , and/or a wet tensile cross-direction (CD) strength of about 15-75 N/m. 
     
     
         8 . The lined pouch material of a tobacco product according to  claim 6 , wherein the lined pouch material comprises longitudinal edge portions essentially free of liner, such that a longitudinal seam of a pouched tobacco product essentially free of liner may be formed when folded into a tubular form of the lined pouch material. 
     
     
         9 . The lined pouch material of a tobacco product according to  claim 8 , wherein the lined pouch material comprises spaced apart discrete regions of liner, such that longitudinal and transverse seams of a pouched product essentially free of liner may be formed from the lined pouch material. 
     
     
         10 . The lined pouch material of a tobacco product according to  claim 8 , wherein said web and liner are laminated. 
     
     
         11 . A method of making a laminated lined pouch material of a pouched tobacco product, comprising superposing ribbons of saliva-permeable water-insoluble web and discrete separately-formed water-soluble liner while drawing them through an embossing apparatus. 
     
     
         12 . The method according to  claim 11 , wherein forming a pouched tobacco product comprises sealing overlapping portions of the web that are essentially free of said liner so as to achieve seams with a web-to-web relation. 
     
     
         13 . The method according to  claim 11 , wherein longitudinal overlapping portions of the web are sealed. 
     
     
         14 . The method according to  claim 11 , wherein transverse overlapping portions of the web are sealed. 
     
     
         15 . A method of making a pouched tobacco product, comprising:
 disposing a separately-formed multilayer liner having a water-soluble layer along a saliva-permeable water-insoluble web; and   enclosing a tobacco component with the web and liner such that the liner is interposed between the tobacco component and the web, wherein the multilayer liner includes a first layer that is water-soluble and comprises water dissolvable flavorant, and wherein a second layer of the multilayer liner comprises a porous moisture resistant layer.
