Abstract: A multi-ply tissue paper product includes at least three plies. The tissue paper product includes a first inner ply being a creped ribbed ply and having a basis weight of 10 to 30 gsm, and a first outermost ply and a second outermost ply on each side of said inner ply, the first and second outermost plies being non-ribbed plies, wherein a creped ribbed ply is a ply including ribs and valleys providing an average core roughness Rk in the range 10 to 300 ?m, and peaks being 4 to 12 per cm as measured along said first direction; and wherein a non-ribbed ply is a ply displaying no parallel ribs and valleys extending continuously along any direction of the ply or displaying parallel ribs and valleys extending continuously along any direction of the ply, the ribs and valleys providing peaks being less than 4 per cm.

Abstract: A multi-ply tissue paper product includes at least two plies made of tissue paper base-sheet with at least one outer ply being a structured outer ply produced by a structuring manufacturing method. The structured outer ply includes a microstructure pattern on substantially at least 80% of the structured outer ply surface. The microstructure pattern is applied by micro-embossing during a converting operation. The structured outer ply is chosen from a through air dried ply produced by a through air drying (TAD) manufacturing method; a dried ply produced by an advanced tissue molding system (ATMOS), or a dried ply produced by a structured tissue technology (SST) manufacturing method. The microstructure pattern includes a first series of protuberances having a density ranging from approximately 30 to 100 protuberances/cm2. The softness property of the structured outer ply is adjusted during a micro-embossing step.
