A reclosable bag that can be hermetically sealed. The bag comprises a pair of zipper strips that are joined in respective zones without substantial deformation of the longitudinal profiled closure elements. These zones of zipper strip joinder assist in providing a leakproof transition from the openable section of the zipper to the corner seals, where the longitudinal profiled closure elements are either substantially deformed (e. g. , crushed) or absent. The method of manufacture involves the steps of ultrasonically welding a wide area and then thermally crushing a narrower area overlapping the wide welded area to form leakproof zipper joints. This method can be applied to string (flangeless) zippers as well as flanged zippers.
