An octagon shaped bulk bag comprising:
- eight double layer side wall portions disposed in an octagonal array and each comprising a stiffening panel receiving pocket;
- eight stiffening panels each received in the stiffening panel receiving pocket comprising one of the side wall portions;
- means for retaining the stiffening panels in the stiffening panel receiving pockets;
- a bottom wall extending between and connected to the bottom of each of the side wall portions;
- the bulk bag further comprising four side wall assemblies each comprising an inner fabric layer, an outer fabric layer, and spaced apart, vertically extending seams defining one of the side wall portions and two half side wall portions each extending outwardly from one of the vertically extending seams, the four side wall assemblies being sewn together end to end thereby connecting the half side wall portions to define the remaining four side wall portions.
A method of manufacturing octagon shaped bulk bags including the steps of:
- providing eight substantially identical fabric sheets each having upper, lower, and side edges;
- arranging the eight fabric sheets in four pairs each comprising an inner layer and an outer layer with the upper, lower, and side edges of each pair respectively aligned;
- joining the inner and outer layers comprising each pair by seams extending parallel to the side edges and spaced apart to define a side wall assembly comprising a stiffening panel receiving pocket extending between the parallel seams and two half stiffening panel receiving pockets each extending outwardly from one of the parallel seams;
- joining the inner and outer layers comprising the four pairs side edge to side edge to form four additional stiffening panel receiving pockets each comprising two half stiffening panel receiving pockets joined edge to edge;
- providing an octagon shaped bottom wall;
- securing the bottom wall to the lower edges of the inner and outer layers comprising each side wall portion;
- providing eight substantially identical stiffening panels;
- and
- positioning a stiffening panel in each of the stiffening panel receiving pockets.
