Abstract
There is provided an elastic laminate of a base layer with one or more attached elastic elements forming an elastic region. The elastic region width varies from a terminal end of the elastic tab to a proximal end of the elastic tab such that a width adjacent the terminal end is 20 to 80 percent narrower than a width adjacent the proximal end. The elastic region is defined by a plurality of segments, having differing average widths in the length direction of the elastic tab elastic region. The one or more elastic elements vary in one or more properties such that a plurality of the segments having different widths have substantially the same degree of elongation at a given elongation of the shaped elastic tab laminate.
