A bag comprising; (a) two film sections of thermoplastic material in overlying relationship, each section having a top edge, a bottom edge joined with the bottom edge of the other section, and two lateral edges spaced between the top edge and bottom edge; (b) a closure element adjacent to and extending across the entire top edge of each section, with the closure elements of overlying sections constructed and arranged in opposing and occludable relationship; (c) a peripheral bead seal coextensive with each lateral edge completely fusing together the overlying sections and the closure elements at each lateral edge; (d) an upper flat seal fusing together adjacent surfaces of the sections in a portion extending inwardly from each bead seal between the top edges of the sections and the uppermost edge of the closure elements; and (e) a lower flat seal fusing together adjacent surfaces of the sections in a portion extending inwardly from each bead seal between the joined bottom edges of the sections and the lowermost edge of the closure elements, such that a flat seal does not extend through the closure elements.
