【Task】 An aqueous composition is applied to a surface, and the surface is irradiated with photochemical rays in the presence of water to form a cured film, which is low extractable from a uniform aqueous photochemically cured composition. A method for producing a film package, comprising a water-soluble compound having at least one α, β-ethylene-based radiation-polymerizable unsaturated group and water as essential components and extractable by a food analog Or its residual component is less than 50 ppb.
