Metallization under vacuum, on at least one face of a plastic film so as to give a substrate including a metallic surface, which substrate is sufficiently electrically conductive to permit a uniform electrochemical deposit. The latter is carried out by electrochemical plating, of at least one metal, on the metallized surface starting from an electrolytic solution, so as to give a thin metallic film having a metal thickness between 0.1 and 4 microns. The metallized substrate is selected so as to be compatible and to facilitate the step of electrochemical plating. The thin metallic sheet obtained is adherent to and supported by the plastic film. The metallic sheet may be used as current collectors for polymer electrolyte lithium batteries, as multi-layer film used as wrapping material permeable to gases and humidity, as a screen for light, flexible conductors, etc.
