These types of side gusset bags are produced from a single web. Joining the edges of the web creates a seam that will become a “fin” on the back or offset to the side. If preferred, the fin can also be tacked down to create a “lap seal”. The seam can even be completely disguised by rotating the fin to an edge and sealing all four edges (quad seal bag).
While these styles of bags do not have flat bottom gussets, the bottom of the bag can be folded and glued to create opportunities for added stability or brand identification when the bags are stacked on store shelves (common for large, high volume and heavy bags such as pet food).
