Abstract
Polymer polysaccharide is added to a PVA coating liquid so that a density of the polymer polysaccharide is within the range between 0.05% and 0.5% by weight with respect to the PVA coating liquid. Next, a coating liquid layer is formed on a web by coating the web with the PVA coating liquid to which the polymer polysaccharide is added so that a temperature of the PVA coating liquid is within the range between 20° C. and 40° C. at the coating. Then, the coating liquid layer on the web is dried after it is preliminarily dried so that a temperature of the coating liquid layer is maintained at a temperature that is 3° C. lower than the temperature of the PVA coating liquid or lower for three seconds or more.
