Title:
WATER-DISPERSIBLE SHEET
Document Type and Number:
WIPO Patent Application WO/2018/221016
Kind Code:
A1
Abstract:
The purpose of the present invention is to further improve the balance between the water dispersibility and the surface barrier properties of a water-dispersible sheet provided with, to at least one surface thereof, a filling layer made of methyl cellulose. The purpose is achieved by a water-dispersible sheet having a filling layer made of methyl cellulose on at least one surface of a water-dispersible base material, wherein the water-dispersible base material contains fibrous carboxymethyl cellulose and papermaking fibers having a Canadian standard freeness of 500-750 ml CSF, the fibrous carboxyalkyl cellulose is alkalized, and the viscosity of a 2% solution of the methyl cellulose at 20°C measured by a Brookfield viscometer is 20-30 cps.
