PROBLEM TO BE SOLVED: To improve the protection characteristics of a product against impact forces, easily judge whether or not the product has received impact forces, and further judge the degree of the impact forces applied to the product. SOLUTION: The packaging device consists of an exterior box 4 and cushioning materials 1 mounted to the box 4. In the material 1, an inside cushioning material 2 and an outside cushioning material 3 (3-1, 3-2) are integrally formed so as to be spaced apart, one from another, by a gap (g). The cushioning material 1 is attached to each of the eight corners, upper ones and lower ones, of the box 4 to protect a product 5 inside the box 4 directly and indirectly. And the degree of impact forces can be grasped depending on the amount of the strain of the material 3. |
