Liquid chemical agent package and production method therefor

Abstract

A liquid chemical agent package includes: a package bag obtained by bonding water-soluble films each containing a polyvinyl alcohol resin (A) to each other; and a liquid chemical agent included in the package bag, wherein in a section in a vertical direction relative to bonding surfaces of the water-soluble films, the liquid chemical agent package contains 20 or more inorganic particles each having a particle diameter of 2 μm or more in a sealed sectional portion having a range extending from an interface between the bonding surfaces by ±10 μm in the vertical direction and having a width of 900 μm. The liquid chemical agent package has water solubility but also high adhesiveness of a water-sealed portion and is hence excellent in sealability, and is hardly affected over time from the end of water application to water sealing and hence maintains high sealability.
