Abstract
(EN) This disclosure relates to a tissue paper product, such as toilet paper or household towel. The tissue paper product comprises at least three plies including a top ply and a bottom ply, as outermost plies, and an inner ply located between the top ply and the bottom ply. A basis weight of the tissue paper product is in a range of 30 to 150, optionally 30 to 100 g/m2, or 35 to 80 g/m2, or 40 to 65 g/m2. The top ply is embossed with at least two types of embossments including first embossments with a first height and second embossments with a second height, the first height being larger than the second height, and the bottom ply is embossed. The inner ply and the top ply are bonded with the bottom ply at tips of the first embossments with an adhesive, such as a lamination glue, or the inner ply, the top ply, and the bottom ply are ply-bonded with mechanical bonding. At least one of the top ply and the bottom ply has been embossed by a heated embossing roll.
(FR) La présente divulgation concerne un produit à base de ouate de cellulose, tel que du papier toilette ou de l'essuie-tout. Le produit à base de ouate de cellulose comprend au moins trois plis incluant un pli supérieur et un pli inférieur en guise de plis les plus à l'extérieur, et un pli interne situé entre le pli supérieur et le pli inférieur. Un poids de base du produit à base de ouate de cellulose se trouve dans une plage de 30 à 150, éventuellement de 30 à 100 g/m2, ou de 35 à 80 g/m2, ou de 40 à 65 g/m2. Le pli supérieur est gaufré avec au moins deux types de reliefs comprenant des premiers reliefs présentant une première hauteur et des seconds reliefs présentant une seconde hauteur, la première hauteur étant supérieure à la seconde hauteur, et le plis inférieur étant gaufré. Le pli interne et le pli supérieur sont collés au plis inférieur au niveau de pointes des premiers reliefs avec un adhésif, tel qu'une colle de contre-collage, ou le pli interne, le pli supérieur et le pli inférieur sont collés entre eux par liaison mécanique. Le pli supérieur et/ou le pli inférieur ont été gaufrés par un rouleau de gaufrage chauffé.
