Product assembly comprising a display strip and a product enclosed bag with a biaxial orientated film

Abstract

[Problem to be Solved] To provide a display strip capable of attaching by heat sealing bags comprising a biaxial oriented film and having no low-melting-point layer on the outer surface of the bag. [Solution] In the display strip comprising a substrate layer and a sealant layer, problems can be solved by using the display strip characterized in that the sealant layer contains an acid-modified olefin resin. In particular, it is more preferable that the sealant layer contains (a) an acid-modified olefin resin, (b) a non-acid-modified olefin resin and (c) an adhesion-imparting agent.

1 - 13 . (canceled) 
     
     
         14 . A product assembly comprising
 (1) a display strip comprising at least a substrate layer and a sealant layer, wherein the sealant layer comprises a mixture of an acid-modified olefin resin and a non-acid-modified olefin resin, and   (2) product-enclosed bags comprising a biaxial oriented film having no low-melting-point polymer layer on the outer surface of the bag,
 wherein the outer surface of the bag is attached by heat fusing on the sealant layer of the display strip. 
   
     
     
         15 . The product assembly as set forth in  claim 14 , wherein an adhesion-imparting agent is added to the sealant layer of the display strip. 
     
     
         16 . The product assembly as set forth in  claim 14 ,
 wherein the acid-modified olefin resin is a resin copolymerized by polyethylene, polypropylene, a copolymer of ethylene or propylene with other α-olefins, or an ethylene-vinyl acetate resin with unsaturated carboxylic acid or acid anhydride thereof, or   a resin graft copolymerized by polyethylene, polypropylene, a copolymer of ethylene or propylene with other α-olefins, or an ethylene-vinyl acetate resin with unsaturated carboxylic acid or acid anhydride thereof.   
     
     
         17 . The product assembly as set forth in  claim 14 , wherein the non-acid-modified olefin resin is polyethylene, polypropylene, a copolymer of ethylene or propylene with other α-olefins, or an ethylene-vinyl acetate resin. 
     
     
         18 . The product assembly comprising
 (1) a display strip comprising at least a substrate layer and a sealant layer, the sealant layer comprising (a) an outermost layer and (b) an adhesive layer on its inner side,
 the outermost layer of the sealant layer comprising a mixture of an acid-modified olefin resin and a non-acid-modified olefin resin, and 
   (2) product-enclosed bags comprising a biaxial oriented film having no low-melting-point polymer layer on the outer surface of the bag,
 wherein the outer surface of the bag is attached by heat fusing on the sealant layer of the display strip. 
   
     
     
         19 . The product assembly as set forth in  claim 18 , wherein an adhesion-imparting agent is added to the sealant layer of the display strip. 
     
     
         20 . The product assembly as set forth in  claim 18 ,
 wherein the acid-modified olefin resin is a resin copolymerized by polyethylene, polypropylene, a copolymer of ethylene or propylene with other α-olefins, or an ethylene-vinyl acetate resin with unsaturated carboxylic acid or acid anhydride thereof, or   a resin graft copolymerized by polyethylene, polypropylene, a copolymer of ethylene or propylene with other α-olefins, or an ethylene-vinyl acetate resin with unsaturated carboxylic acid or acid anhydride thereof.   
     
     
         21 . The product assembly as set forth in  claim 18 , wherein the non-acid-modified olefin resin is polyethylene, polypropylene, a copolymer of ethylene or propylene with other α-olefins, or an ethylene-vinyl acetate resin. 
     
     
         22 . The product assembly as set forth in  claim 18 , wherein a silicone treating agent layer is provided between the outermost layer and the adhesive layer on its inner side.
