Patent

CA 2231173

A multi-ply paper product wherein the plies are adhesively joined together is disclosed. 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.

L'invention concerne un papier comprenant plusieurs couches jointes ensemble. Une couche ou deux peuvent présenter des bosses dirigées vers une autre couche et venant en contact avec celle-ci. Les couches adhèrent ensemble, de préférence, au niveau des bosses. D'une manière avantageuse, l'adhésif est choisi parmi les compositions assurant une adhérence minimale à l'état humide et une force d'adhérence des couches à l'état sec comprise dans une gamme particulière choisie.
