Patent

CA 2229645

A multi-ply paper product. One or both of the plies may have embossments protruding towards and contacting the other ply. The plies are adhesively joined, preferably at such embossments. The adhesive is selected from a composition that advantageously provides a minimum wet ply bond strength and a dry ply bond strength which falls within a particularly desired range.

Ce produit en papier, à plusieurs couches, comprend, sur une de ces couches ou les deux, des protubérances faisant saillie vers l'autre couche avec laquelle elles entrent en contact. Les couches sont jointes par collage, effectué de préférence sur ces protubérances. L'adhésif est choisi à partir d'une composition ayant l'avantage de procurer une résistance minimum des liaisons entre les couches à l'état humide, et une résistance des liaisons entre ces couches à l'état sec qui tombe dans une fourchette souhaitable.
