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

A coreless roll of a tissue paper product comprises:

• 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 to define an axially extending inner hole centrally positioned relative to the coreless roll 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 two plies, being a first ply and a second ply, the first ply and the second ply being ply-bonded,
• wherein a grammage of the tissue paper product is in a range of 35 to 55 g/m2,
• the tissue paper product has a Geometric Mean Tensile strength of at least 200 N/m, and wherein:
• the first ply and the second ply are made of Conventional Wet Press (CWP) paper,
• the first ply and the second ply have been embossed to be nested,
• 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 70 to 90 kg/m3, and
• a caliper ratio of the roll is in a range of 40% to 70%,
• 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.
