摘要： A polyvinyl alcohol film is provided to realize improved physical properties including tensile strength, elongation, light transmission, gloss and elasticity, as compared with a polyvinyl alcohol film having a single polymerization degree and saponification rate. A polyvinyl alcohol film is obtained by the method comprising blending a low-polymerization degree polyvinyl alcohol polymer having a number average polymerization degree of 1,500-2,000 and a saponification rate of 88-99.9 mole% with a high-polymerization degree polyvinyl alcohol polymer having a number average polymerization degree of 2,200-8,000 and a saponification rate of 99.5-100 mole% in a solvent at a weight ratio of 90:10-10:90, followed by vacuum debubbling, casting, drying and winding.
