Abstract
Abstract An improved free flow packing material particularly characterized by its ability to isolate packed items and to absorb the energy of potentially destructive shocks and impacts, together with a method and means for its manufacture. The individual units of the packing material are structurally in the form of elongate flat ''''bows,'''' wherein two self adhered layers of foamed expanded plastic material form a central portion of the ''''bow'''' and curved outward extensions of these layers form two oppositely extending flat loops. The flat ''''bow'''' shaped units are individually of a size and shape to provide a desired freeflowing characteristic, and are formed of a foamed expanded crushable plastic material which inherently possesses a shock absorbing characteristic. The aligned flat loops and centrally adhered midsection of the ''''bows'''' cooperate to provide unusually shape stable packing units without detracting from the shock absorbing characteristics of a mass of such packing units.
