Abstract
A cushioning material for packaging is formed of a foldable and regenerable sheet, such as a corrugated cardboard or thick paper, and is used to protect an article of a rectangular cross-sectional shape packaged in an outer case. First and third frame members (,) for forming a pair of parallel edge members of a rectangular frame, and second and fourth frame members (,) for forming the other pair of parallel edge members of the same frame are provided, and the frame members (,) are formed of hollow bodies having a plurality of hollow portions (,) arranged in parallel, the contour and sizes of cross sections intersecting the hollow portions (,) being substantially equal. The hollow bodies constituting the frame members (,) are formed in a row by folding corrugated cardboard, thick paper or other foldable sheet, adjacent frame members among frame members (,) being connected to outer side sheet portions (,) positioned on the outer side, when the frame members (,) are assembled into a rectangular frame, the end portions of adjacent frame members out of the frame members (,) having joint structures (,) for combining the frame members together at right angles to each other with the outer side sheet portions (,) left as they are. Therefore, this cushioning material for packaging is rarely deformed, and displays an excellent cushioning effect.
