Abstract
An expansible cellular void filler for dunnage uses is formed of a stack of flat, bendable strips, each except the top and bottom of which is secured at alternating longitudinally spaced positions to an overlying strip and to a subjacent strip, the secured positions being aligned in rows in a direction perpendicular to the planes of the flat strips, the spacing between at least two such rows being less than the spacing between other rows, so that when the strips are moved apart and bend to form cells, the cell sidewalls formed by the portions of the strips which extend between said two rows move toward a straight planar relationship prior to the sidewalls of other cells, and limit the expansion of the filler.
