ABSTRACT:
A method of packaging articles and packaged article assemblies disclosed includes inflating a body such as a latex balloon or a bag with a drawstring preferably by evacuating the air in a chamber surrounding the body while the body is supported and sealed at the fill opening. An initial selected quantity of packaging particles are placed inside the inflated body followed by placing the article therein. The body is collapsed around the particles which distributes them in a substantially uniform layer surrounding the article from all sides and applies compressive forces inwardly from all sides to cushion the article in the body. Another method involves expanding an outer body, placing packaging particles in that body, collapsing that outer body and placing a second body in the outer body followed by expansion of the two and putting a fluid and article in the inner body and sealing the bodies closed. The resulting packaging assembly has an inner body with fluid such as water and preferably a live fish with a layer of particles compressed against the inner body by an outer collapsed body for transporting live fish and the like.
