Process for production of biaxially oriented polyester film |
| abstract |
A process for producing polyester film which is effectively reduced in the disadvantageous lengthwise and widthwise heat shrinkages inherent in biaxially oriented film and which is excellent in flatness and mechanical characteristics. More specifically, a process for the producing of biaxially oriented polyester film which comprises subjecting a biaxially oriented polyester film which has been drawn in the lengthwise and widthwise directions and heat-treated to widthwise relaxation and lengthwise relaxation by a method of shortening the clip intervals, wherein the biaxially oriented polyester film is held under stretching between the widthwise relaxation step and the lengthwise relaxation step. |
