Abstract
A process for producing a metallized plastic film comprising the steps of applying a masking oil supplied from an oil supply source to the surface of a rubber roll drivingly in rotation and having formed on its surface projections or indentations in conformity with the margin pattern to be formed, applying the masking oil on the surface of the rubber roll to the surface of a plastic film in a pattern substantially similar to the margin pattern, and forming a vacuum-evaporated metal film on the oil bearing surface of the plastic film. Margins can be formed in a desired pattern efficiently by this process.
