ABSTRACT:
A paper bag is formed from a single sheet of paper by folding the same to produce a final generally rectangular bag or receptacle with an open end. The upper edge portion around the bag opening is folded in and glued to provide greater strength thereat. During the folding and glueing of this opening strength turned-in collar, two carrying handles are also glued in, one on each of the bag's largest sides. According to this invention, a corner portion at one end of the turned-in collar portion is cut out and enables glueing thereat to an inner surface rather than the typically smoother outer surface of the paper, thereby providing improved strength to the reinforced opening of the bag.
