Abstract

L’invention a pour objectif de surmonter le problème d’insalubrité accompagnant le suintement de la morve vers la face arrière des papier-mouchoirs. Le papier-mouchoir selon l'invention a une structure à deux ou trois couches, chacune des couches (11), (12), et (30) étant une couche de papier constituée de pâte, et présente un suintement d’au plus 10 mg d’une morve artificielle vers la face arrière lors d’un test de suintement de la morve artificielle (pas de chargement).
