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.
