Method for producing crystalline polyolefin resin film |
| abstract |
Disclosed is a method for producing a crystalline polyolefin resin film capable of suppressing unevenness in thickness and colored defects of the obtained crystalline polyolefin resin film, and capable of suppressing breakage of a lip of a T die. The method for producing a crystalline polyolefin resin film according to the present invention comprises a step of extruding a crystalline polyolefin resin from a lip of a T die and forming it into a film shape, and the crystalline polyolefin resin from the T die. The extrusion is stopped and the lip surface temperature is higher than 60 ° C. until the extrusion start point at which the extrusion of the crystalline polyolefin resin from the T die starts. Hold in an inert gas atmosphere at 80-180 ° C. [Selection] Figure 1 |
