The reclosable zipper fastener is cut to a length sufficient to overly the removable portion. A splotch seal is formed at the ends of the reclosable zipper by applying heat and pressure to yield a flattened, broadened segment at each of said opposed distal ends. The splotch sealed fastener is attached to the flexible material by forming a continuous perimeter seal (26) around tho removable portion between the fastener and the flexible material.
