  • Publication number: 20180271719
    Abstract: The present disclosure is directed, in part, to an absorbent article including a topsheet including a second substrate disposed at least partially intermediate a first discrete substrate and a third discrete substrate. The first discrete substrate opposes the third discrete substrate about a longitudinal axis of the topsheet. The first discrete substrate and the second discrete substrate are bonded in a first bonding zone about a longitudinal axis of the topsheet. The third discrete substrate and the second discrete substrate are bonded in a second bonding zone about a longitudinal axis of the topsheet. A pair of leg cuffs have free terminal edges and are joined to the topsheet and/or backsheet. The distance between the free terminal edges is not longer than the distance between an inner edge of the first bonding zone and an inner edge of the second bonding zone.
