ABSTRACT:
Air encapsulating cellular material in which failure due to the rupture of individual ones of the cells thereof is substantially prevented. The material comprises a sheet defining a plurality of air encapsulating cells in a substantially uniform pattern. At least a pair of adjacent cells are in flow communication so that upon direct pressure to one of such cells, the air may be displaced and can flow to the adjacent cell. In this manner, air pressure build up in one cell which may otherwise have resulted in its rupture, is prevented.
