ABSTRACT:
A foil has two essentially plane parallel surfaces of which at least one is at least partially covered by a metallic layer. The surface of the metallic layer is protected by an antifriction film. The surface opposite the metal-coated surface of the foil can likewise be protected by an antifriction film. The antifriction film or films should have a uniform thickness of at most 0.5 micron. The antifriction film or films can be vapor deposited, rolled or sprayed on to the foil or distributed on the foil ultrasonically or electostatically. The foil is subsequently wound into a roll.
