Abstract: A method for handling product enclosures each containing a product and having a through opening. A five panel fiberboard folder is provided that includes first, second, third, fourth and fifth elongate panels each having opposite longitudinally extending sides, one longitudinally extending side of the fourth panel being joined to one longitudinally extending side of the third panel, and the longitudinally extending side of the fourth panel opposite the third panel being joined to one longitudinally extending side of the fifth panel. The fifth panel has a plurality of through cuts between its major surfaces each defining a hook portion of the fifth panel projecting toward a first end of the fifth panel, and the five panel folder has perforations affording separation of the fourth panel from between the third and fifth panels.
