| 摘要 | An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer. And, the first outer layer may comprise an amount of draw down polymer greater than about 45 wt %. | ||||||
