Abstract

A bag includes a first and second panel; first and second layflat side edges; a bottom edge; and a bag mouth; at least one of the layflat side edges, and the bottom edge, includes a radiation cured adhesive layer bonding the first and second panels together. A thermoformed container includes a forming web and a substantially non-forming web; and a radiation cured adhesive layer disposed between and bonding at least portions of the forming web and the substantially non-forming web. A film/foam composite includes a thermoplastic film and a polymeric foam sheet; and a radiation cured adhesive layer disposed between and bonding at least portions of the thermoplastic film and the polymeric foam sheet. An inflatable packaging cushion includes a plurality of flexible plastic sheets bonded together in the region of their edges; a radiation cured adhesive layer bonds at least a portion of the flexible plastic sheets together.

Claims

exact text as granted — not AI-modified
1 . A bag comprising: 
 a) a first panel;    b) a second panel;    c) first and second layflat side edges;    d) a bottom edge; and    e) a bag mouth;    wherein at least one of the first and second layflat side edges, and the bottom edge, comprises a radiation cured adhesive layer bonding the first and second panels together.    
   
   
       2 . The bag of  claim 1  wherein the bag panels each comprise a film having an oxygen barrier layer, and a bonding layer.  
   
   
       3 . The bag of  claim 1  wherein the average thickness of the radiation cured adhesive layer is from 0.1 to 12 micrometers.  
   
   
       4 . The bag of  claim 1  wherein the radiation cured adhesive forms a pattern.  
   
   
       5 . The bag of  claim 1  wherein the radiation cured adhesive forms a discontinuous layer.  
   
   
       6 . A thermoformed container comprising: 
 a) a forming web, the forming web comprising a polymeric material;    b) a substantially non-forming web comprising a polymeric material; and    c) a radiation cured adhesive layer disposed between and bonding at least portions of the forming web and the substantially non-forming web.    
   
   
       7 . The thermoformed container of  claim 6  wherein the forming web and the substantially non-forming web each comprise a film having an oxygen barrier layer, and a bonding layer.  
   
   
       8 . The thermoformed container of  claim 6  wherein the average thickness of the radiation cured adhesive layer is from 0.1 to 12 micrometers.  
   
   
       9 . The thermoformed container of  claim 6  wherein the radiation cured adhesive layer forms a pattern.  
   
   
       10 . The thermoformed container of  claim 6  wherein the radiation cured adhesive forms a discontinuous layer.  
   
   
       11 . A film/foam composite comprising: 
 a) a thermoplastic film comprising a polymeric material;    b) a polymeric foam sheet; and    c) a radiation cured adhesive layer disposed between and bonding at least portions of the thermoplastic film and the polymeric foam sheet.    
   
   
       12 . The film/foam composite of  claim 11  wherein the thermoplastic film comprises a layer comprising a polyolefinic material.  
   
   
       13 . The film/foam composite of  claim 11  wherein the average thickness of the radiation cured adhesive layer is from 0.1 to 12 micrometers.  
   
   
       14 . The film/foam composite of  claim 11  wherein the radiation cured adhesive layer forms a pattern.  
   
   
       15 . The film/foam composite of  claim 11  wherein the radiation cured adhesive forms a discontinuous layer.  
   
   
       16 . An inflatable packaging cushion comprising a plurality of flexible plastic sheets bonded together in the region of their edges, wherein a radiation cured adhesive layer bonds at least a portion of the flexible plastic sheets together.  
   
   
       17 . The inflatable packaging cushion of  claim 16  wherein the flexible plastic sheets each comprise a layer comprising a polyolefinic material.  
   
   
       18 . The inflatable packaging cushion of  claim 16  wherein the average thickness of the radiation cured adhesive is from 0.1 to 12 micrometers.  
   
   
       19 . The inflatable packaging cushion of  claim 16  wherein the radiation cured adhesive forms a pattern.  
   
   
       20 . The inflatable packaging cushion of  claim 16  wherein the radiation cured adhesive forms a discontinuous pattern.
