Abstract: A bag having a front side, a rear side, and left and right sides connecting the front and rear sides. When folded, the bag comprises a first simple gusset in at least one of the left and right sides and at least a second gusset in at least one of said left and right sides, wherein the second gusset is selected from the group consisting of a second simple gusset and a compound gusset formed from the first simple gusset. Preferably, the simple and compound gussets are formed in both left and right sides. The bag may comprise a plurality of simple gussets, compound gussets, and combinations thereof.

Abstract: A system comprising a multiple-bag pack supported for dispensing, loading, and removal of bags on a structure. The pack includes a bag-attachment portion wherein the multiple bags are sequentially attached. Each bag is removable in sequence by separation from the pack along a parting feature. The bags are contained within the structure and the bag-attachment portion is folded outwards over a lip to secure the bag pack. The front edge of the outermost bag of the pack is drawn over another lip to open the bag for loading. The rear edge remains attached to the bag pack, thus fully distending the mouth of the bag. To change bags, the rear edge of the bag is separated from the pack and the first lip along the parting structure. The front edge of the loaded bag is removed from the second lip, and the bag is closed and removed from the structure.
