PROBLEM TO BE SOLVED: To obtain a low-cost cushioning material which compensates for a poor restorable demerit of foamed styrol and increases the merit farther, by constituting the cushioning material with a resin cushioning material made of foamed styrol resin having a load receiver and a cardboard cushioning box in which the resin cushioning material is charged to closely stick thereto. SOLUTION: This cushioning material A used for packaging or the like of products is constituted of a resin cushioning material 1 made of foamed styrol and a cardboard cushioning box 2. The resin cushioning material 1 is formed so that the outside face shape thereof has almost the same shape with the inside face shape of the cardboard cushioning box 2. And a load receiver 3 is formed to receive the shock load of an objective, in the resin cushioning material 1. And a load receiver 4 corresponding to the load reveiver 3 is formed in the cardboard cushioning box 2 side as well. Even if the cushioning material A is formed of a fragile and low-foaming styol material, since the cardboard cushioning box 2 prevents the resin cushioning material 1 from cracking against external forces, the shape can be semipermanently retained. |
