Method of producing biaxially stretched polyester film |
| abstract |
The present invention improves the bowingnphenomenon of a biaxially stretched polyester film whichncomprises stretching the longitudinally stretched cast filmnlaterally at a temperature higher than the glass transitionntemperature of the polyester film from by 5 °C to by 50 °C,nstaying the laterally stretched film in an intermediate zone for anperiod from 3 to 30 seconds which has been controlled at antemperature from higher than the lateral stretchingntemperature by 20 °C or more to lower than a heat settingntemperature by 20 °C or less, and then heat-setting at the heatnsetting temperature which is lower than the melting point ofnthe polyester film from by 30 °C to by 5 °C. |
