Abstract
A method of vacuum depositing a layer on a plastic film in which the film is transported so as to pass along a metal surface moving with the film, which surface removes heat from the film, and vacuum depositing the vapor of an evaporant onto the surface of the plastic film while it is in contact with the metal surface. The film is in an electret state when it is located at the metal surface, whereby an electrostatic attractive force is produced between the film and the metal surface, thereby increasing the efficiency of heat conduction between the film and the metal.
