Abstract

This invention is to obtain a polyvinyl alcohol-based polymer film that has a smooth cut end face having a low degree of roughening in the whole length of the film, causes neither cracks nor breaks at a cut end face when uniaxially oriented in the length direction and is suitable as a rolled web film in producing a polarizing film. The method for obtaining the film comprises cutting the polyvinyl alcohol-based polymer film in the length direction by using a rotary round blade.
