Abstract

In accordance with some embodiments, a label material attachable to a product and a method of applying the label material to the product are described. In some embodiments, a label material may include a polyurethane web including a top side and a back side, an adhesive applied to the back side, and a removable backing. The adhesive may have a melting temperature of less than 170 degrees Celsius.

What is claimed is: 
     
         1 . A label material comprising:
 a polyurethane web comprising a top side and a back side;   an adhesive applied to the back side; and   a removable backing,   wherein the adhesive has a melting temperature of less than 170 degrees Celsius.   
     
     
         2 . The label material of  claim 1 , wherein the polyurethane web is comprised of a polyurethane resin. 
     
     
         3 . The label material of  claim 2 , wherein the polyurethane resin is substantially free of raw fabric. 
     
     
         4 . The label material of  claim 1 , wherein the polyurethane web is substantially transparent. 
     
     
         5 . The label material of  claim 1 , further comprising at least one printed indicia printed onto the polyurethane web. 
     
     
         6 . The label material of  claim 5 , wherein the at least one printed indicia is printed on the top side of the polyurethane web. 
     
     
         7 . The label material of  claim 5 , wherein the at least one printed indicia comprises at least one of: a brand, an image, a logo, a theme, or a set of care instructions. 
     
     
         8 . The label material of  claim 1 , wherein the adhesive is positioned between the back side and the removable backing. 
     
     
         9 . The label material of  claim 1 , wherein the polyurethane web is bonded or applied to a product. 
     
     
         10 . The label material of  claim 1 , wherein the adhesive is a polyurethane thermo-adhesive. 
     
     
         11 . The label material of  claim 1 , wherein the polyurethane web is divided or cut into a plurality of individual labels. 
     
     
         12 . A method of applying a label material to a product comprising the steps of:
 supplying the label material to a printer;   printing at least one indicia on a polyurethane web of the label material;   removing a backing from the polyurethane web to expose an adhesive;   cutting the polyurethane web into a plurality of individual labels;   positioning at least one of the plurality of individual labels on the product; and   activating the adhesive,   wherein the adhesive has a melting temperature of less than 170 degrees Celsius.   
     
     
         13 . The method of  claim 13 , wherein the at least one of the plurality of individual labels is substantially translucent except for the at least one indicia printed thereon. 
     
     
         14 . The method of  claim 13 , wherein the at least one printed indicia comprises at least on of: a brand, an image, a logo, a theme, or a set of care instructions. 
     
     
         15 . The method of  claim 13 , wherein activating the adhesive comprises applying heat and pressure to the at least one of the plurality of individual labels. 
     
     
         16 . The method of  claim 16 , wherein the heat is less than 170 degrees Celsius and the pressure is within a range of between 1.3 and 1.5 kg/cm 2 . 
     
     
         17 . A label attachable to a product comprising:
 a polyurethane web portion comprised of a top side and a back side;   an adhesive for attaching the polyurethane web portion to the product; and   a removable backing portion,   
       wherein the adhesive has a melting temperature of less than 170 degrees Celsius. 
     
     
         18 . The label of  claim 18 , wherein the polyurethane web portion comprises at least one printed indicia.
