Coreless rolls of a tissue paper product and methods of manufacturing coreless rolls

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, the web of tissue paper product being 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,

• wherein the tissue paper product comprises three plies, the three plies being a first ply, a second ply, and a third ply, wherein the first ply is one of the outermost plies of the tissue paper product, and the three plies are ply-bonded, optionally using an adhesive such as lamination glue and/or mechanical bonding, such as edge embossing, to form the tissue paper product, and
• wherein the grammage of the tissue paper product is in a range of 34 g/m2 to 65 g/m2, optionally 40 g/m2 to 63 g/m2, or 45 g/m2 to 60 g/m2, and wherein
• the first ply is made of Conventional Wet Press (CWP) paper,
• the second ply is a structured paper ply, such as a ply made of TAD, UCTAD, eTAD, Atmos, or NTT, and
• the first ply has been embossed with a heated embossing roll,
• the coreless roll has an outer diameter in the range of 95 to 150 mm, a diameter of the inner hole is in the range of 20 to 50 mm, and a density of the coreless roll is in a range of 90 to 150 kg/m3, and
• a caliper ratio of the roll is in a range of 20% to 60%,
• the caliper ratio (cs−ct)/ct being obtained by dividing a difference between a standard caliper cs of the tissue paper product as defined by the standard ISO-12625-3:2014 and a theoretical caliper ct of the tissue paper product by the theoretical caliper ct, and
• the theoretical caliper ct being defined as a ratio between a grammage of the tissue paper product and the density of the roll.

• wherein the tissue paper product comprises four plies, the four plies being a first ply, a second ply, a third ply, and a fourth ply, wherein the first ply is one of the outermost plies of the tissue paper product, and the four plies are ply-bonded, optionally using an adhesive such as lamination glue and/or mechanical bonding, such as edge embossing, to form the tissue paper product, and
• the grammage of the tissue paper product is in a range of 55 g/m2 to 95 g/m2, or optionally 60 g/m2 to 80 g/m2, and wherein
• the first ply is made of Conventional Wet Press (CWP) paper,
• the second ply is a structured paper ply, such as a ply made of TAD, UCTAD, eTAD, Atmos, or NTT, and
• the first ply has been embossed with a heated embossing roll,
• the coreless roll has an outer diameter in the range of 95 to 150 mm, a diameter of the inner hole is in the range of 20 to 50 mm, and a density of the coreless roll is in a range of 110 to 150 kg/m3, and
• a caliper ratio of the roll is in a range of 12% to 40%,
• the caliper ratio (cs−ct)/ct being obtained by dividing a difference between a standard caliper cs of the tissue paper product as defined by the standard ISO-12625-3:2014 and a theoretical caliper ct of the tissue paper product by the theoretical caliper ct, and
• the theoretical caliper ct being defined as a ratio between a grammage of the tissue paper product and the density of the roll.
