Abstract
The present invention relates to a composite laminated structure comprising a substrate and an apertured layer joined together by means of a layer of an adhesive composition. The laminated structure is made extensible in designated zones by mechanical straining and the adhesive composition provides both an effective connection of the layers forming the composite laminated structure and an improved processability of the laminated structure by mechanical straining. The composite laminated structure preferably constitutes side flaps in a disposable absorbent article such as a sanitary napkin.
