Method for producing a foil material provided with an embossed hologram as well as a foil material

Abstract

The invention relates to a method for producing a foil material, provided with an embossed hologram. Said method comprises the following steps: optionally metallizing said material, applying a lubricant and then directly embossing said material, the embossed surface remaining the material top layer. Said invention also relates to a foil material having the following structure: a metal layer, provided with an embossed hologram, and a lubricant layer, which is at least partially applied to said metal layer, whereby said material top layer is exclusively formed by the metal layer and/or the lubricant layer.

1 . Method for producing a foil material provided with an embossed hologram and having a metal layer, comprising the following steps: 
 applying a lubricant, and    directly thereafter embossing the material, the embossed surface remaining the topmost layer of the material.    
     
     
         2 . Method according to  claim 1 , wherein the material is an aluminium foil, an aluminium-paper composite or metallized paper.  
     
     
         3 . Method according to  claim 1  wherein the lubricant is applied in an order of magnitude of 0.02 g/m 2 .  
     
     
         4 . Method according to  claim 1 , wherein a cutting process occurs in a single operation together with embossing, which is followed by winding onto at least one roll.  
     
     
         5 . Foil material comprising 
 a metal layer having an embossed hologram therein,    a lubricant layer which is at least partially applied to said metal layer, wherein    the topmost layer of the material is formed exclusively by the metal layer and/or the lubricant layer.    
     
     
         6 . Foil material according to  claim 5 , wherein the material is a metallized paper, an aluminium foil or an aluminium-paper composite.  
     
     
         7 . Foil material according to  claim 5  wherein the material has a lubricant layer in an order of magnitude of 0.02 g/m 2 .  
     
     
         8 . Foil material according to  claim 5 , wherein the material is a roll of material.
