ABSTRACT:
A packaging system includes an outer bag having an inner bag suspended therein to define an expandable chamber between the bags and one either side of the inner bag. When the chamber is charged with a filler medium, such as pressurized air, the outer bag will inflate to suspend the inner bag at a fixed position therein. The inner bag defines a pocket adapted to receive and retain an article, prepackaged therein.
