Abstract

A bottom gusseted bag includes first and second opposed walls that face one another, each of the first and second walls having an upper end and a lower end, and a gusseted bottom that connects the bottom ends of the first and second walls to one another. The gusseted bottom includes at least four panels that are formed from an open mesh material and that collectively form at least three pleats. Opposed side edges of all of the panels are thermally bonded directly to one another along first and second opposed seams extending at least the majority of the length of each of the panels. The gusseted bottom may have a side seam strength of at least about 1.lb (4.5 N). The first and second side walls are formed at least in part of material, such a film, that is thermally bondable to the mesh material.
