Polyvinyl alcohol film and method for producing polyvinyl alcohol film |
| abstract |
Disclosed are a stretched polyvinyl alcohol film and a method for producing such a film. Particularly disclosed is a stretched polyvinyl alcohol film which is prevented from shrinking under wet conditions and thus has excellent workability and mechanical strength, and a method for producing such a film. More specifically disclosed is a stretched polyvinyl alcohol film wherein a degree of shrinkage between before and after a film treatment, wherein the film is immersed in water at 20°C for 10 hours and then dried at 30°C for 30 minutes, is at most 3 % in the longitudinal direction and at most 3 % in the lateral direction. |
