Abrégé
(EN)
A stretch laminate includes a first layer including an elastomer film, the first layer having a surface, and a second layer including a nonwoven material, the second layer having a basis weight of less than about 25 gsm and a surface that is attached to the surface of the first layer. The elastomer film has a strength of an engineering tensile strength, at an engineering strain rate of about 600/s, of at least one of about greater than about 14 MPa for a plain specimen or about greater than about 7 MPa for a notched specimen. A method of making the stretch laminate and an absorbent article having at least one region defined by the stretch laminate are also provided.

L'invention concerne un stratifié étirable, comprenant une première couche comprenant un film élastomère, la première couche ayant une surface, et une seconde couche comprenant un matériau non tissé, la seconde couche ayant un poids de base inférieur à environ 25 g/m2 et une surface qui est attachée à la surface de la première couche. Le film élastomère a une résistance à la traction, à un taux de contrainte d'environ 600/s, supérieure à environ 14 MPa pour un échantillon normal et supérieure à environ 7 MPa pour un échantillon entaillé. L'invention concerne également un procédé de fabrication du stratifié étirable et un article absorbant ayant au moins une région définie par le stratifié étirable.
