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. L'invention concerne un procédé de fabrication d'un film isolant métallisé à double surface, se caractérisant en ce qu'il consiste à pulvériser un gaz d'oxydation sur un film déposé sur une surface intérieure du film isolant enroulé sur un rouleau au cours d'un processus de déposition sous vide de zinc ou d'un mélange de zinc et d'aluminium sur les deux surfaces du film isolant, et à enrouler le film isolant sur le rouleau, formant un film d'huile sur au moins une surface et exposant au moins un film déposé sur un côté à l'atmosphère contenant de l'oxygène sur au moins un film déposé pour former un film oxydé au cours d'un processus d'enroulement sur le rouleau, éliminant ainsi un système de blocage selon lequel les films déposés sur les deux surfaces adhèrent l'un à l'autre et sont séparés l'un de l'autre dans le rouleau.
