Abstract A perforated laminate (10) comprising at least first (12) and second layers (14) and apertures (16) extending through at least the first layer (12). The first layer (12) is a nonwoven or formed film material, and the second layer (14) comprises an absorbent structure. The at least first (12) and second layers (14) are primarily joined at the periphery of the perforated apertures (16). The laminate (10) is particularly useful as a topsheet for an absorbent article, such as a disposable diaper or sanitary napkin. Also described are various materials and methods used to create such laminates. Un lamellé perforé comprend au moins des première et deuxième couches et des ouvertures traversant au moins la première couche. La première couche est un non tissé ou un matériau sous forme de film et la deuxième couche comprend une structure absorbante. Les première et deuxième couches ou plus sont tout d'abord liées au niveau du pourtour des ouvertures perforées. Le lamellé est tout particulièrement utile en tant que feuille supérieure pour un article absorbant tel qu'une couche jetable ou une serviette hygiénique. Cette invention porte également sur diverses matières et divers procédés utilisés pour créer de tels lamellés.
