Abstract
The invention provides a method for manufacturing a processed plastic film, which involves reducing the amount of charge on a plastic film traveling in a vacuum. In particular, the method includes a step for removing charge by a charge removal method in which a conductor having a radius of curvature of 1 mm or less is installed near the plastic film in the width direction of the plastic film, the shortest distance between the surface of the plastic film and the conductor is set to 2-10 mm, and the grounded conductor is used while maintaining the pressure therebetween at 8-800 Pa.
