Abstract
To provide a non-moisturizing high-grade type tissue paper having excellent softness.The problem is solved by a 3-ply tissue paper having a basis weight of 12.0 g/m2 or more per ply, having a paper thickness of 200 to 265 μm for three plies, having a water content of 4.0 to 9.0% by mass, containing 0.15 to 0.45% by mass of an oily component to be extracted with diethyl ether, and having a bending rigidity of less than 0.006 gf·cm/cm in CD (Cross Direction) and a bending recovery force of less than 0.005 gf·cm/cm in CD.
Claims
exact text as granted — not AI-modified1 . A 3-ply tissue paper, comprising 0.15 to 0.45% by mass of an oily component to be extracted with diethyl ether,
wherein the tissue paper has a basis weight per ply of 12.0 g/m 2 or more, a paper thickness for three plies of 200 to 265 μm, a water content of 4.0 to 9.0% by mass, a bending rigidity of less than 0.006 gf·cm/cm in machine direction, and a bending recovery force of less than 0.005 gf·cm/cm in machine direction.
2 . The tissue paper according to claim 1 , which has a dry tensile strength of 300 to 440 cN in cross direction and a dry tensile strength of 130 to 200 cN in machine direction.
3 . The tissue paper according to claim 1 ,
wherein a polyol is not externally applied.
4 . The tissue paper according to claim 1 , comprising no glycerin.Cited by (0)
