The invention concerns an absorbent paper product with basic weight of about 36 to about 105 g/m2comprising at least three pleats, a first and second outer embossed pleats each comprising raised patterns consisting at least partially of discrete protuberances oriented towards the inside of the structure and a non-embossed central pleat, the pleats being associated by linking the distal surfaces of at least part of the protuberances of each of the outer pleats to the central pleat. The invention is characterised in that each of the embossed outer pleats is linked by means of an adhesive to said central pleat, and at least one of the pleats has a pattern density more than 30 protuberances per cm2.
