<p>A packaging buffer material (1) includes a pair of outer sidewalls (11) having concave grooves (14) formed in central portions in a length direction and an outer bottom wall (12) having a concave groove (15) formed in a central portion in the length direction. Stoppers (20), preventing a packing object (40) from being displaced, are attached between inner sidewalls (16) opposed to the respective outer sidewalls (11) and an inner bottom wall (17) opposed to the outer bottom wall (12). If external pressure is applied to the packaging buffer material (1), the outer sidewalls (11) and concave groove bottoms (18) are deformed. However, because of narrow widths of the concave groove bottoms (18), the outer sidewalls (11) are not entirely deformed but only the concave groove bottoms (18) are deformed.</p> |
