摘要： This disclosure relates to a coreless roll of a tissue paper product, such as toilet paper, made of a spirally wound continuous web of tissue paper product having a first end and a second end and having an outer diameter in the range of 95 to 150 mm. The web of tissue paper product is wound such as to define an axially extending inner hole centrally positioned relative to the coreless roll and such that the first end is located on the outer side of the coreless roll and the second end is located at the inner hole. A diameter of the inner hole is in the range of 20 to 50 mm. A density of the coreless roll is in a range of 80 to 150 kg/m3. A caliper ratio of the roll is in a range of 10% to 80%. The tissue paper product comprises between two and four plies, wherein the plies are ply-bonded. At least one ply is made of Conventional Wet Press paper (CWP), and at least one ply is a structured ply. The grammage of the tissue paper product is in a range of 24 g/m2 to 125 g/m2.

摘要： This disclosure relates to a tissue paper product, such as toilet paper or household towel. The tissue paper product comprises between two and four plies, including at least a first ply and a second ply. The two plies, three plies, or four plies are ply-bonded, optionally using an adhesive such as lamination glue or mechanical bonding, such as edge embossing, to form the tissue paper product. The first ply and the second ply are the outermost plies of the tissue paper product. A grammage of the tissue paper product being in a range of 24 to 50 g/m2 if a total number of plies of the tissue paper product is 2, in a range of 34 to 65 g/m2 if a total number of plies of the tissue paper product is 3, and in a range of 55 to 95 g/m2 if a total number of plies of the tissue paper product is 4. The first ply is made of Conventional Wet Press (CWP) paper and has been embossed with a heated embossing roll. The second ply is a structured paper ply, such as a ply made of TAD, UCTAD, eTAD, Atmos, or NTT.
