Abstract: A stackable flexible bulk container includes a bag portion of woven polypropylene and is comprised of a bottom wall, a top wall and an encircling side wall. At least two lifting strap loops are provided so that the container can be lifted by the tongs of a forklift truck. To enable the tongs to enter the loops without manual assistance, relatively rigid devices are associated with the ends of the loops to hold them upright and opened. The loops are also held outwardly away from the center of the bag so that similar containers can be stacked without interfering with the loops of the container below.
