Absorbent article having flap activation

An absorbent article such as a sanitary napkin, adult incontinence device, or the like. The absorbent article has a pair of flaps for securing the absorbent article. The flaps extend laterally outward from the main body portion of the article. The flaps are associated with the main body portion at a juncture along the longitudinal edges of the main body portion. The flaps have a notch. The flaps have at least one first zone of anisotropic stiffness contiguous with the notch. The first zone of anisotropic stiffness has a relatively stiffer direction and a relatively less stiff direction. The first zone of anisotropic stiffness can be made of corrugated or ring-rolled portions of the absorbent article.
