| titleOfInvention | Method for producing biaxially stretched film |
| abstract | (57) [Summary] [PROBLEMS] In a method of biaxially stretching a sheet obtained by using a cooling roll on a microcrack surface, a high-quality film having excellent smoothness and no orange-skin-like defects is stable at high speed for a long time. The present invention provides a method for producing a biaxially stretched film that can be produced by the following method. SOLUTION: A molten polymer is extruded into a sheet form from an orifice-shaped die, and is adhered to a cooling roll on the surface of a microcrack to be solidified to form an unstretched sheet. Then, the unstretched sheet is biaxially stretched in the longitudinal and transverse directions. A method for producing a stretched film, comprising: biaxially stretching the film so that the product of the stretching ratio in the machine direction and the transverse direction is 15 to 100 times. |
