A composite plastic film comprises a plastic film which is coated, as desired at least on one side, with ceramic material deposited using a vacuum thin layer deposition process and a plastic layer deposited by extrusion coating on the plastic film or on the ceramic layer which may be present, such that the ceramic layer is situated between the plastic film and the plastic layer deposited by extrusion coating. In order to improve the strength of bonding, a metal layer of chromium, aluminum, nickel, titanium, iron, molybdenum or an alloy made up from at least two of these metals is provided, as an aid to bonding, between the plastic film or on the ceramic layer which may be present and the plastic layer deposited by extrusion coating. A thin metal layer deposited in such an amount that it has a thickness of approximately 0.1 to 0.5 nm corresponding to a monatomic coverage is sufficient for this purpose.
