徴とする梱包用の緩衝ブロツク。 By bending a sheet of paper board, a polygonal cylindrical shape or a modified cylindrical buffer frame based on that shape is formed, with both ends meeting at one corner, and extension pieces at both ends of the paper board are formed. Bend it inward and bring both bent parts together, and use the extension pieces to form a main brace for reinforcing the buffer outer frame.A sub-bracing that intersects with the main brace is formed separately from paper board material. A shock absorbing block for packaging, characterized in that cut grooves are formed so as to be inserted and assembled with each other, and the shock absorbing outer frame is held in contact with both bent portions at the one corner by combination with sub-bracings. .
