资源简介：
The purpose of the present invention is to improve the balance between the water dispersibility and the surface barrier property of a water-dispersible sheet having a sealing layer comprising methylcellulose on at least one surface. The water-dispersible sheet with an improved balance between the water dispersibility and the surface barrier property can be obtained by using methylcellulose having a specific viscosity in the sealing layer. Provided is a water-dispersible sheet having a sealing layer comprising methylcellulose on at least one surface of a water-dispersible base paper， wherein the water-dispersible base paper comprises fibrous carboxymethyl cellulose and papermaking fiber with 500 to 750 ml CSF of Canadian standard freeness， the fibrous carboxyalkyl cellulose is alkalized， and the viscosity of a 2% aqueous solution of the methylcellulose measured by a Brookfield viscometer at 20 degree C. is 20-30 cps.
