Foil packaging

Abstract

A foil packaging for soft food masses includes a container film shape-formed into the form of an open container and a lidding film which is sealed onto the container film closing the container with a lid. The container film and lidding film are multi-layered and one of the layers is an aluminum foil, which is optionally pre-lacquered and if desired printed on and lacquer-coated on one side. The aluminum foil of the container film and the lidding film is coated with a polymer and a hot-sealing lacquer is provided on the polymer layer of the container film. The polymer, optionally coated with hot-sealing lacquer, may be situated on the sealing side of the aluminum foil of the lidding film, and a corrosion protection layer, if desired in the form of a polymer, is provided on the other side of the aluminum foil. Alternatively, the aluminum foil of the lidding film may be coated on the sealing side with hot-sealing lacquer and the polymer layer, optionally coated with hot-sealing lacquer, is situated on the other side of the aluminum foil.

         7 . A foil packaging for soft foodstuffs, comprising a container film shaped into the form of an open container featuring a hot-sealing layer and a lidding film that is sealed into the hot-sealing layer of the container film and closes the open container with a lid, wherein the container film and the lidding film are multi-layered and include a layer which is an aluminum foil, wherein:
 the aluminum foil is coated with a polymer to provide a polymer layer, whereby the hot-sealing layer is situated on the polymer layer of the container film and, alternatively:   a) the polymer layer is situated on the sealing side of the aluminum foil of the lidding film and a corrosion protection layer is provided on the other side of the aluminum foil; or   b) the aluminum foil of the lidding film is coated on the sealing side with a hot-sealing lacquer and the polymer layer is situated on the other side of the aluminum foil.   
     
     
         8 . A foil packaging according to  claim 7 , wherein the aluminum foil of the container film and the aluminum foil of the lidding film each independently exhibit a thickness of 5 to 15 μm. 
     
     
         9 . A foil packaging according to  claim 7 , wherein the aluminum foil of the container film and the aluminum foil of the lidding film each independently exhibit a thickness of 6 to 11 μm. 
     
     
         10 . A foil packaging according to  claim 7 , wherein the aluminum foil of the container film or the lidding film or both the container film and the lidding film is pre-lacquered on one side. 
     
     
         11 . A foil packaging according to  claim 7 , wherein the aluminum foil of the container film or the lidding film or both the container film and the lidding film is printed on and lacquered over. 
     
     
         12 . A foil packaging according to  claim 7 , wherein the polymer layer is coated with a hot-sealing lacquer. 
     
     
         13 . A foil packaging according to  claim 7 , wherein the corrosion protection layer is in the form of a polymer. 
     
     
         14 . A foil packaging according to  claim 7 , wherein the aluminum foil of the container film or the lidding film or both the container film and the lidding film is coated with polymer in a weight per unit area of about 1-10 g/m 2 . 
     
     
         15 . A foil packaging according to  claim 7 , wherein the aluminum foil of the container film or the lidding film or both the container film and the lidding film is coated with polymer in a weight per unit area of about 2-8 g/m 2 . 
     
     
         16 . A foil packaging according to  claim 7 , wherein the polymer is a polyolefin. 
     
     
         17 . A foil packaging according to  claim 7 , wherein the polymer is a polyethylene or polypropylene. 
     
     
         18 . A foil packaging according to  claim 7 , wherein the polymer is an ionomer.
