Insulated label

Abstract

The invention is an insulated label for maintaining the temperature of the contents of a package, formed from a polymeric thermoplastic closed cell foam having from about 5,000 to about 250,000 closed cells per cubic inch.

1 . An insulated label for maintaining the temperature of the contents of a package, the insulated label comprising: 
 a polymeric thermoplastic closed cell foam having first and second surfaces and from about 5,000 to about 250,000 closed cells per cubic inch.    
   
   
       2 . The insulated label according to  claim 1 , wherein the polymeric foam is a polymeric microfoam formed from a solution flash extrusion process microfoam.  
   
   
       3 . The insulated label according to  claim 1 , wherein the foam has from about 25,000 to about 100,000 closed cells per in 3 .  
   
   
       4 . The insulated label according to  claim 1 , wherein the foam has from about 25,000 to about 75,000 closed cells per in 3 .  
   
   
       5 . The insulated label according to  claim 1 , wherein the foam has from about 40,000 to about 60,000 closed cells per in 3 .  
   
   
       6 . The insulated label according to  claim 1 , wherein the foam has a thickness of at least about 0.25 mm.  
   
   
       7 . The insulated label according to  claim 1 , wherein the foam has a thickness of from about 1 to about 4 mm.  
   
   
       8 . The insulated label according to  claim 1 , wherein the foam comprises extruded polypropylene, polyethylene, or mixtures thereof.  
   
   
       9 . The insulated label according to  claim 1 , further comprising a printable film layer affixed to the first surface.  
   
   
       10 . The insulated layer according to  claim 9 , further comprising a layer of adhesive between the foam and the film layer.  
   
   
       11 . The insulated layer according to  claim 9 , further comprising a layer of adhesive on the second surface.  
   
   
       12 . An insulated container, comprising the insulated label according to  claim 1 .  
   
   
       13 . A method of making an insulated package or container, the method comprising obtaining a label according to  claim 1 , and 
 affixing the label onto a package or container.    
   
   
       14 . A method of making an insulated package or container, the method comprising obtaining a label according to  claim 9 , and 
 affixing the label onto a package or container.
