Cyclic olefin resin film and method for producing the same |
| abstract |
The present invention provides a method capable of improving the brittleness of an unstretched intermediate base film and stably producing a cyclic olefin resin film. SOLUTION: A cyclic olefin resin is extruded into a film at an extrusion temperature of 230 to 260 ° C. and a melt viscosity of 500 to 3000 Pa · S. The film 12A is wound up by the winder 26. Next, the film 12B is delivered from the delivery machine 32, and the film 12B is stretched by the longitudinal stretching section 34 and the lateral stretching section 40 to develop retardation, thereby producing the optical film 12C.
