Abstract

La présente invention concerne des bandes plastiques perforées souples, tridimensionnelles, qui laissent passer la vapeur d'eau et, de préférence, l'air, mais bloquent les fluides au moins dans un sens. Ces bandes plastiques perforées sont constituées d'un film polymère imperméable aux liquides muni de perforations capillaires dont la longueur est au moins le double de celle de perforations correspondantes pratiquées à la surface du film polymère. L'invention concerne également des articles absorbants, tels que des couches pour bébés ou des articles pour adultes incontinents et, notamment, des serviettes hgiéniques ou protège-slips comportant une couche supérieure sur la surface tournée vers l'usager, pendant l'utilisation. Selon l'invention, ces articles sont également munis d'une couche de support utilisé, de préférence, pour sa respirabilité. La couche de support comprend au moins une couche constituée de la bande plastique perforée souple, tridimensionnelle, de l'invention.
