Method for producing stretched film |
| abstract |
An object of the present invention is to provide a method for producing a stretched film that can sufficiently reduce thickness unevenness after stretching even for a film having poor thickness accuracy. A stretched film manufacturing method including the following conditions (i) and (ii). (I) After the surface temperature of the film-like acrylic polymer exceeds the glass transition temperature (Tg), the film is stretched by 50 to 95% of the total stretching ratio until reaching the maximum temperature in all steps. (Ii) After the surface temperature of the film-like acrylic polymer reaches the maximum temperature in all steps, the film is stretched by 5 to 50% of the total stretching ratio while lowering the surface temperature. [Selection figure] None |
