Absorbent articles having a unique elastic feature improving the dynamic fit as well as containment characteristics. The elastic feature preferably comprises an elastomeric member and a nonelastic web; a portion of the nonelastic web coincides with at least a portion of the elastomeric member; this portion of the nonelastic web being mechanically prestrained. Mechanical prestraining of the nonelastic web improves not only the extension of the elastomeric member, but also the heat-shrink contraction of preferred elastomeric members.

Articles absorbants présentant un élément élastique unique premettant un ajustement dynamique amélioré ainsi que de meilleures caractéristiques de retenue. L'élément élastique comprend de préférence un élément élastomère et un voile non élastique, une partie de ce dernier coïncide avec au moins une partie de l'élément élastomère, et est soumise à une précontrainte mécanique. La précontrainte mécanique du voile non élastique améliore non seulement l'extension de l'élément élastomère, mais également la contraction par rétrécissement à chaud des éléments élastomères préférés.
