Title:
METHOD FOR MANUFACTURING PROCESSED PLASTIC FILM
Document Type and Number:
WIPO Patent Application WO/2022/264921
Kind Code:
A1
Abstract:
[Problem] To provide a method for manufacturing a processed plastic film, the method comprising a charge removal step for preventing damage to a charged plastic film due to abnormal discharge and eliminating problems with plastic film travel due to electrostatic adhesion by removing the charge on the plastic film using a simple device and lowering the potential at the surface. [Solution] The problem can be solved by a method which is for manufacturing a processed plastic film and reduces the amount of charge on a plastic film traveling in a vacuum, the method comprising a step (step 1) 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.
