Abstract: A method of manufacturing an SOS bag of indefinite length is disclosed including, as a preliminary step, providing a gusseted tube of indefinite length. In a series of steps, the gusseted tube may be cut, trimmed, folded, and sealed to create a unique bottom for an SOS bag. The bottoms of the front panel and the rear panel may be cut so as to permit the inward folding of the bottoms of the gussets of the gusseted tube, such that the bottoms of the gussets overlap. A front panel of the gusseted tube may then undergo a trimming and folding and heat sealing, followed by the rear panel of the gusseted tube undergoing a trimming and folding and heat sealing. The disclosure additionally includes bags manufactured by the method disclosed herein, as well as SOS bags having the unique construction disclosed herein.
