Abstract

A water-soluble film contains a polyvinyl alcohol resin (A), and has a complete dissolution time (T) and a curl area percentage (S), wherein a product (T×S) of the complete dissolution time (T) and the curl area percentage (S) satisfies the following expression (1):1000≤(Complete dissolution time ())×(Curl area percentage ())≤7000  (1)The water-soluble film satisfies contradictory property requirements, i.e., satisfactory solubility and curl suppressing property, for example, even if being formed by using an acid-modified PVA resin.
