Abstract
PURPOSE:To obtain a film having no surface defect and excellent running performance, by stretching a polyester film containing a small amount of a polyalkylene glycol with rolls after subjecting this film to corona discharge treatment of a specified E value. CONSTITUTION:An unstretched polyester film containing 0.01-1.8wt.% polyalkylene glycol (e.g., polyethylene glycol) (e.g., polyethylene phthalate film) is subjected to corona discharge treatment of an E value of 10-60 and then stretched with rolls. Because a nonsticky hard thin film is formed on the film surface by the corona discharge treatment, the film loses its stickiness to a high-temperature roll during stretching, and problems such as the formation of defects on the film surface and adhesion of sticky matter to it can be eliminated. Said E value can be obtained from W/(D.V) (wherein W is the intensity of treatment, D is the width of treatment, m, and V is the speed of film, m/min).
