Abstract
Expandable bag assemblies and associated methods are disclosed herein. Certain aspects of the invention are directed toward an expandable bag assembly that includes a flexible bag with closed and open ends and collapsible sidewalls disposed between the ends. The assembly beneficially includes an integrated support structure provided with stiffeners and a mechanism for attachment to help hold a mouth of the bag in an open position while filling the bag. The assembly can be compressed for easy packaging and storage and be expanded into a self-supported, open position without memory folds. The assembly is also configured to retract during closure of the open end of the bag.
