TEAR RESISTANT POROUS EXTENSIBLE WEB

摘要

The present invention pertains to a porous, macroscopically-expanded, three- dimensional, elastomeric web suitable for use in disposable absorbent articles such as bandages, diapers and pull-up diaper training pants, as well as a method for making the web. In a preferred embodiment the web has a continuous first surface and a discontinuous second surface remote from first surface. In a preferred embodiment the elastomeric web exhibits a multiplicity of primary apertures in the first surface of the web, the primary apertures being defined in the plane of the first surface by a continuous network of interconnecting members. Each interconnecting member exhibits an upwardly concave-shaped cross section along its length. The interconnecti ng members terminate substantially concurrently with one another to form a secondary aperture in the plane of the second surface of t he web.
