Abstract
A targeted elastic laminate material is provided having at least one low tension zone with first filaments having a first basis weight and at least one high tension zone having second filaments with a second basis weight greater than the first basis weight. The second basis weight is greater due to increased average thickness of the second filaments and/or increased frequency of second filaments relative to the first filaments. Methods and modifications of those methods are provided to produce a targeted elastic laminate material according to the preferred embodiments of this invention.
