Abstract: A sealed pliable bag, or pillow, containing loose particles is adapted for evacuation by means of a valve or by an air tube inserted through the bag which may be heat sealed upon subsequent withdrawal of the air tube. The particle filled bag is placed in contact with an article to be packaged so as to conform with the size and shape of at least a portion of the article and the bag is evacuated. One or more additional particle-filled bags are positioned over a remaining portion of the article and are similarly evacuated. Upon evacuation, the bags undergo a size reduction and become rigid, defining a hollow space conforming to the size and shape of the packaged article with the bags serving to protect the article when positioned in a closed container.

Abstract: An inflatable packaging insert as adapted for positioning around and encapsulating an article disposed in a closed box when inflated for providing support and protection for the article during shipping. The packaging insert includes a pair of spaced, opposed V-shaped or triangular inserts forming a gusset on its inner surface allowing the packaging insert when inflated to securely engage the corners and edges of the article. The gusset allows the inner article-engaging surface of the packaging insert to expand as a generally flat surface so that it engages the entire facing surface of the object including its edges and corners in a generally uniform manner. The packaging insert is preferably comprised of a strong, pliable, gas-impervious material such as polyethylene and includes an integral self-sealing valve for inflation and deflation as well as interconnected compartments or chambers formed by heat, pressure or radio frequency (RF) formed seals.
