Polyvinyl alcohol film, stretched film, and manufacturing method of polyvinyl alcohol film

摘要

A PVA film capable of obtaining a stretched film excellent in stretch processability and good transparency and low phase difference, a method for producing such a PVA film, and a stretched film obtained from such a PVA film are provided. The polyvinyl alcohol film of the present invention contains polyvinyl alcohol (A) and polyisoprene rubber particles (B), and the average particle diameter of the polyisoprene rubber particles (B) is 85 nm or more and 700 nm or less. It is a polyvinyl alcohol film in which the content of the polyisoprene rubber particles (B) is 3 parts by mass or more and 35 parts by mass or less with respect to 100 parts by mass of the polyvinyl alcohol (A).
