Abstract

Lingette humide gaufrée comprenant un élément de base comportant un seul pli de pâte naturelle, l'élément de base ayant une profondeur de 0,5 à 1,0 mm, et un gaufrage doté d'une pluralité de bossages concaves-convexes et formé sur la surface de l'élément de base. L'élément de base étant fabriqué à un seul pli, le procédé de fabrication est très simple. Etant donné qu'aucune colle n'est utilisée, la lingette mouillée gaufrée est inoffensive pour le corps humain. Puisque la profondeur des bossages est de 0,5 à 1,0 mm, la linguette humide gaufrée peut conserver le motif gaufré et avoir un taux d'absorption d'eau suffisant.
