ABSTRACT:
A reclosable standup bag and a method for manufacturing the bag. The bag includes opposing top and bottom panel assemblies. The top panel assembly includes first and second opposing fins having upper edge portions that define a mouth opening. Opposing front and back wall panels extend between the top and bottom panel assemblies. First and second opposing gusseted side wall panels couple and bridge the side edges of the front and back wall panels, defining four wall corners. A resealable closing assembly is coupled to the upper edge portion of the fins. The method for manufacturing the bag includes providing a lay flat web of a flexible packaging material and cutting comer reliefs at the location of the upper side corners of the bag. The lay flat web is run over a forming tube to create a duct-shaped cylinder with overlapping side edges. The side edges are joined and are fin sealed to form a tube having a bottom opening and a top opening. Side gussets are formed, centered about the die cut corner reliefs, leaving the two fins extending along either side of the corner reliefs and over the top opening of the tube. The side edges of each gusset and the bottom opening are sealed. The bottom portion of the tube is folded to form a generally flat bottom portion. A reclosable closing assembly is coupled to the upper edge portions of the first fin and the second fin.
