<p>A method of manufacturing a double surface metallized insulation film, characterized by comprising the steps of spraying oxidation gas on an inner surface side deposited film on the insulation film wound on a product roll in a process for vacuum-depositing zinc or the mixture of zinc and aluminum on both surfaces of the insulation film and winding the insulation film on the product roll, forming an oil film on at least one surface and exposing at least one side deposited film to the atmosphere containing oxygen in a depositing process, or spraying the gas containing oxygen on at least one deposited film to form an oxidized film in the process for winding on the product roll, whereby a blocking that the deposited films on both surfaces are adhered to each other and separated from each other in the product roll can be eliminated.</p> |
