The present invention relates to absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or panty liners which have an aperture film topsheet on the surface facing the wearer in use. According to the present invention the articles are provided also with an apertured backsheet for breathability. The backsheet comprises at least one breathable layer of a resilient, three-dimensional web which consists of a liquid impervious polymeric film having apertures. These apertures form capillaries which are not perpendicular to the plane of the film but are disposed at an angle of less than 90~ relative to the plane of the film.
L'invention concerne des articles absorbants tels que couches pour bébés, garnitures pour adultes incontinents, et surtout serviettes hygiéniques ou protège-slips, qui comportent une feuille supérieure formée d'un film perforé, constituant la surface en contact avec l'utilisateur. Selon l'invention, les articles comportent également une feuille support perforée qui leur confère un caractère imperrespirant. La feuille support comprend au moins une couche imperrespirante comportant une nappe tridimensionnelle résiliente, constituée d'un film polymère imperméable aux liquides et présentant des orifices. Ces derniers forment des capillaires qui ne sont pas perpendiculaires au plan du film, mais disposés selon un angle inférieur à 90· par rapport audit plan.
