Date Jun. 5, 1986.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 of the foil opposite the metal-coated surface 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 electrostatically. The foil is subsequently wound into a roll.
