Abstract

An absorbent article such as a sanitary napkin has a cover, a baffle and an absorbent between the cover and baffle and includes an embossed channel in the absorbent. The channel is positioned inward from the absorbent edge. The channel impedes the flow of fluid toward the edges of the absorbent article and increases absorbent utilization in the absorbent article.
