Abstract
Absorbent articles having a unique elastic feature improving the dynamic fit as well as containment characteristics. The elastic feature preferably includes 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.
