Abstract: A bag holding system includes a stand, such as a header A-frame stand, or a beltboard. The stand includes a slot for receiving a tab defined on a bag assembly adapter. The bag assembly adapter also includes at least one first connector member for connecting with a second connector member defined on a bag assembly such as a saddle pack. The saddle pack is formed from a number of stacked polymeric sheets each including a first bag, a second bag, and a center strip portion having a first edge connected to the first bag and a second edge connected to the second bag. The second connector member includes an aperture extending through the center strip portions. The at least one first connector member of the bag assembly adapter may include a leg portion having a nub projecting through the aperture of the bag assembly so as to secure the bag assembly to the bag assembly adapter.
