Patent

CA 2203647

The present invention relates to disposable absorbent articles such as baby diapers or sanitary napkins having a breathable yet liquid leakage retarding backsheet. In particular the backsheet comprises an inner and an outer layer which are essentially non-attached to each other. Both layers can be formed of the same or a different breathable material and preferably replace a single breathable material at parity material consumption.

L'invention concerne des articles absorbants jetables tels que des couches pour bébés ou des serviettes hygiéniques, comportant une feuille arrière respirante mais évitant toute fuite des liquides. En particulier, la feuille arrière se compose d'une couche intérieure et d'une couche extérieure qui ne sont pas fixées l'une à l'autre. Les deux couches peuvent être formées du même matériau respirant ou d'un matériau différent, et remplacent, de préférence, un matériau respirant unique avec une consommation de matériau égale.
