Abstract
Abstract In several alternative embodiments, soft flexible edge-sealing film extending about the sides of an absorbent pad is shown fastened to the bottom ply and also fastened to the exterior or interior surface of the facing ply, joined integrally with the facing ply or extrusion bonded to the facing ply. The edge seal strips are optionally flocked or faced with tissue for further softness. The separately fabricated edge-sealing strips may have properties or qualities differing from those of the backing, examples being softness, pliability, pin strength, and cost.
