A reclosable bag is formed of walls defining a closure with a mouth. The closure includes a male profile extending along an internal surface of one of the walls and a female profile adapted to interengage with the male profile and extending along an internal surface of the other wall. The male and female profiles are extruded from a polymeric resin. At least one of the male and female profiles includes at least one rib of another polymeric material coextruded therewith and extending longitudinally therealong. The polymeric material of the rib has a lower melting point than the polymeric material of the profiles, so that it will melt when a side seal is made transversely across the closure and will flow into and caulk any openings remaining after the interlocked profiles have been flattened.
