Abstract

A water-soluble film includes a polyvinyl alcohol resin (A) as a main component, wherein the ratio (X/X) of a degree of elongation (X) in the transverse direction (TD) of the water-soluble film to a degree of elongation (X) in the machine direction (MD) thereof when the water-soluble film is floated on the surface of water at 20° C. for 60 seconds is from 1.05 to 1.5. The water-soluble film exhibits reduced curling, exhibits reduced positional shift, and shows satisfactory sealability while forming a package.
