         4 . The surface covering according to  claim 3 , wherein the top facing layer comprises a single layer of polyvinyl chloride film. 
     
     
         5 . The surface covering according to  claim 4 , wherein the single layer of polyvinyl chloride film has a thickness of about 0.075 mm to 0.1775 mm. 
     
     
         6 . The surface covering according to  claim 1 , wherein the top facing layer comprises a paper stock. 
     
     
         7 . The surface covering according to  claim 1 , wherein the top facing layer of polymeric film is thermally fused to the bottom layer of unsupported foam. 
     
     
         8 . The surface covering according to  claim 1 , further comprising an adhesive layer in-between the top facing layer of polymeric film and the bottom layer of unsupported foam. 
     
     
         9 . The surface covering according to  claim 1 , further comprising an embossed pattern on the top facing layer of polymeric film. 
     
     
         10 . The surface covering according to  claim 1 , wherein the bottom layer of unsupported foam comprises a polymeric compound having a diffusion of minuscule gas bubbles. 
     
     
         11 . The surface covering according to  claim 10 , wherein the polymeric compound is selected from a group consisting of latex, polyvinyl chloride, polyurethane and ethylene vinyl acetate. 
     
     
         12 . The surface covering according to  claim 1 , wherein the bottom layer of unsupported foam has a thickness of about 1.275 mm to 1.675 mm. 
     
     
         13 . The surface covering according to  claim 10 , wherein the bottom layer of unsupported foam is configured with a fine pattern of micro-embossed indentations. 
     
     
         14 . The surface covering according to  claim 10 , wherein the bottom layer of unsupported foam has a smooth continuous surface. 
     
     
         15 . The surface covering according to  claim 1 , wherein the surface covering is a shelf liner, a drawer liner and/or a storage container liner. 
     
     
         16 . A method of manufacturing a surface covering comprising the steps of:
 supplying a sheet of polymeric film as a top sheet and a sheet of polymeric foam as a bottom sheet;   simultaneously transporting the sheet of polymeric film and the sheet of polymeric foam under a laminating unit;   thermally combining the sheet of polymeric film to the sheet of polymeric foam to form therein, the thermal combining step resulting in a composite material;   cooling the composite material; and   cutting a grid of perforations into the composite material,   wherein,
 the composite material comprises an upper layer sheet of polymeric film 
 and a bottom layer of polymeric foam. 
   
     
     
         17 . The method of manufacturing the surface covering according to  claim 16 , further comprising the step of embossing an upper surface of the sheet of polymeric film. 
     
     
         18 . The method of manufacturing the surface covering according to  claim 16 , further comprising the step of applying an adhesive to an underside of the polymeric film and contacting the underside of polymeric film to the polymeric foam before simultaneously transporting the sheet of polymeric film and the sheet of polymeric foam under the laminating unit.
