ABSTRACT:
An empty square bottom bag is provided which consists of a front wall, a back wall and a bottom wall formed from a unitary panel and including a band of adhesive on the outer face of said panel extending along the marginal edge portion of each side panel, the panels being folded inwardly so that the band of adhesive on one side panel is disposed at an interface with another side panel and thereby secures the side wall panels with respect to one another in an overlapping relationship to close opposite sides of the bag and retain front, bottom and back walls in an open U-shaped configuration.
