Abstract (en)
To provide a method for manufacturing three-ply or four-ply tissue paper that reduces a sticky feeling of an outer surface while securing necessary softness.In manufacturing tissue paper including a stacked sheet in which three plies or four plies are stacked, each of the plies contains an aqueous moisturizer exhibiting hygroscopicity, and each of the plies has a difference in magnitude of an arithmetic mean height Sa according to ISO 25718 between both surfaces of each of the plies. A manufacturing method includes: applying the moisturizer to each of the plies such that the moisturizer is applied to an outer surface of each of the plies located on an outer side of the stacked sheet in a state where the outer surface has a small value of the arithmetic mean height Sa; folding the stacked sheet in which the moisturizer has been applied to each of the plies; and then storing the stacked sheet in the storage body in a folded state.
