Tissue paper products, rolls and stacks of tissue paper products, and manufacturing methods

A method of manufacturing a tissue paper product, such as toilet paper or household towel, comprising at least three plies, comprising the steps of:

• feeding at least three plies, including a first ply, a second ply, and a third ply, with a basis weight in the range of from 13 to 30 g/m2, optionally 16 to 28 g/m2, or 18 to 24 g/m2, respectively;
• embossing the first ply on a first embossing roll with embossing protrusions with a first height h1 to form first embossments on the first ply,
• embossing the first ply on a second embossing roll with second embossing protrusions with a second height h2, the first height h1 being larger than the second height h2, wherein the embossing on the second embossing roll is carried out before or after the embossing on the first embossing roll;
• embossing the second ply on a third embossing roll with embossing protrusions with a third height h3;
• ply-bonding the first ply, the second ply, and the third ply, and optionally further plies, such that the first ply and the second ply are outermost plies and the third ply is an inner ply, using an adhesive, such as a lamination glue, and/or water, and/or mechanical bonding, such as edge embossing;
• wherein the inner ply is not embossed, and
• wherein at least one of the first embossing roll, the second embossing roll, and the third embossing roll is a heatable roll.

• embossing the first ply on a primary embossing roll with first embossing protrusions with a first height h1 to form first embossments on the first ply and with second embossing protrusions with a second height h2, the first height h1 being larger than the second height h2;
• embossing the second ply on a secondary embossing roll with embossing protrusions with a third height h3;
• ply-bonding the first ply, the second ply, and the third ply, and optionally further plies, such that the first ply and the second ply are outermost plies and the third ply is an inner ply, using an adhesive, such as a lamination glue, and/or water, and/or mechanical bonding, such as edge embossing;
