摘要： 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 T × ( Curl area percentage S ) ≤ 7000 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.
