  • Publication number: 20070049888
    Abstract: An absorbent core comprises a multi-microlayer film having a plurality of coextruded microlayers that can perform the multiple functions of acquisition, retention and distribution of fluids. The multi-microlayer films may be formed in a coextrusion process. Each microlayer is manufactured from either a high-recovery polymer or a low-recovery polymer and may be in a substantially alternating configuration within the film. A disruptive force, such as a stretching force, can be applied to at least one portion of the multi-microlayer film to partially delaminate the low-recovery microlayer from the high-recovery microlayer to form corrugations in that portion. The multi-microlayer film can be apertured and additives may be included in either polymer layer.
