Water-soluble film and package

Abstract

[Problem to be solved] To provide a water-soluble film capable of suppressing formation of holes when used as a package while maintaining water solubility, and a package using such a water-soluble film. [Solution] A water-soluble film containing a polyvinyl alcohol resin, wherein within a square A1 with a side of 1 cm or more and 5 cm or less positioned at an arbitrary location on at least one surface of the water-soluble film, each side of an area of square A2 with a side of 5 μm is divided into 64 to divide the entire area into 4096 pixels, and when elastic moduli of the pixels are measured by an atomic force microscope, a number average value of the elastic moduli of the pixels is 1 to 200 MPa, and a coefficient of variation of the elastic moduli of the pixels is 0.1 to 0.7.
