摘要： The present invention provides a method for producing a dehydrating sheet comprising two films at least one of which is a polyvinyl alcohol film, and a high osmotic pressure material interposed between the films, wherein the polyvinyl alcohol film is formed by a stretching treatment after extrusion molding, followed by a heat treatment at 150 to 250° C. and a water treatment. According to the present invention, it is possible to provide a dehydrating sheet comprising a polyvinyl alcohol film which has excellent water permeability, is prevented from forming pinholes, and is not significantly expanded or shrunk due to the absorption of water.
