Insulating label stock

Abstract

An insulating label stock including a thermal insulating layer, which may be a fiberfill batt, is provided. The batt is laminated to at least one layer of film, paper, or fabric. Also provided is a method of making insulating label stock. The insulating label stock may be wrapped around a container, such as a can, bottle, or pouch. Further, the insulating label stock may be coated with a coating material so that it is printable, thus imparting both insulating properties and print capability to a container.

       26 . The method of  claim 14 , wherein the face material is a film comprising a first layer and a second layer that is heat sealable, and wherein the heat sealable second layer is adhered to the surface of the thermal insulating layer.  
   
   
       27 . The method of  claim 14 , further comprising the step of cutting the label stock to desired widths, lengths or widths and lengths.  
   
   
       28 . The method of  claim 27 , wherein the label stock is cut to desired widths, lengths or widths and lengths with a hot knife which seals the edges of the thermal insulating layer and the face material so that fluid cannot penetrate the edges of the insulating label.  
   
   
       29 . The method of  claim 14 , further comprising the step of folding the label stock back onto itself, so that the top and bottom edges are sealed.  
   
   
       30 . The method of  claim 14 , wherein the face material is treated with a corona discharge.
