摘要: An improved process for surface modification of polyethylene terephthalate film is provided, involving corona discharge treatment of the film in an atmosphere of nitrogen containing up to about 350 ppm oxygen, and optionally a small amount of acetone vapor. Films so treated exhibit improved surface properties.
