GUSSETED BAG ABSTRACT OF THE DISCLOSURE A gusseted bag is provided which, according to a preferred mode, is constructed of thermoplastic multilayer film with an outer sealing layer and has a seamless folded bottom and reverse-fin-sealed sides. Advantageously, the starting material for such bags is lay-flat tubular film cut longitudinally along the center of one side, which is folded and joined to itself along each side of the longitudinal cut, respectively. In an alternate mode wherein the bag bottom is not seam- less but is end-sealed, the bag is constructed by joining together two such lay-flat tubes along each side of their longitudinal cuts, respec- tively.
