A film that comprises a mixture of a block copolymer and a polyethylene polymer. One embodiment of such a film is a film comprising a block copolymer selected from the group consisting of poly(styrene)-co-poly(ethylene-butylene)-co-poly(styrene) copolymer and poly(styrene)-co-poly(ethylene-butylene) copolymer, and a polyethylene polymer. The film exhibits improved self-adhesive properties and is suitable for use in a disposable absorbent product intended for the absorption of fluids such as body fluids. Cette invention porte sur un film comprenant un mélange fait d'un copolymère séquencé et d'un polymère de polyéthylène. Dans un mode de réalisation, le film comporte un copolymère séquencé issu du groupe constitué par un copolymère de poly(styrène)-co-poly(éthylène-butylène)-co-poly(styrène), par un copolymère de poly(styrène)-co-poly(éthylène-butylène) et par un polymère de polyéthylène. Ce film, qui fait montre de caractéristiques auto-adhésives améliorées, convient à des articles absorbants jetables conçus pour absorber des liquides tels que des liquides organiques.
