Abstract
A method for producing a double-sided evaporation film by forming metal-containing evaporation films on both surfaces of a non-magnetic plastic substrate film by an evaporation system with an evaporation drum, includes, in the following order: forming a metal-containing evaporation film on a first surface of the substrate film; forming an organic substance film on the metal-containing evaporation film; and forming a metal-containing evaporation film on a second surface of the substrate film, the second surface being opposite to the first surface.
