An improved reclosable fastener assembly is disclosed having a substantially C-shaped closure element which defines a channel, and a first arm and second arm extending from the ends thereof. Clasps are disposed on the ends of the arm portions which extend inwardly. A U-shaped closure element is further provided which has a curved centrally disposed portion and a pair of legs extending angularly outward from the center of the interior surface from the center line. The legs each have a hook on their end which extend laterally outward. A pair of bumpers are disposed on the base of the U-shaped member with a curved exterior portion between the end of the hook and the bumper on each side. The closure elements are constructed and arranged for reclosably fastening to each other over a predetermined length. One or more ribs are centrally disposed on the C-shape closure element which abut against the first and second legs and the curved portion during interlocking. In addition, the ribs further serve to align and maintain the positioning of the closure elements during sealing of the fastener assembly to one or more webs of plastic films in the manufacture of reclosable plastic bags.
