[Industrial applications]

 The present invention relates to a cushioning material for packaging which is composed of paper materials such as cardboard and can be easily developed and assembled.

[0002]

[Prior art and its problems]

 Styrofoam is generally used as the cushioning material for packaging in the past, but styrofoam is bulky, consumes a large amount of money, and has a high packaging cost. Also, since it is not easy to incinerate, pollution due to disposal has become a problem.

Recently, a cushioning material that can be assembled from paper materials has been proposed (see, for example, Japanese Utility Model Laid-Open No. 4-45266), and the cushioning material made of paper materials becomes bulky by dismantling after use, Further, since it is made of paper, it can be easily incinerated, and the problems of the foamed polystyrene cushioning material can be eliminated. However, the conventional paper cushioning material is divided into five parts: a case material, a pair of front and rear frame materials, and a pair of left and right reinforcing materials, which results in poor workability during packaging and material consumption. However, the effect of reducing the packaging cost was not yet sufficient.

The present invention has been made for the purpose of eliminating such conventional problems.
