  The cushioning member made of cardboard sheet is formed by cutting the cardboard sheet into a predetermined shape and then bending it. For this reason, there is a problem that the manufacturing cost is high because the number of processing steps is relatively large and the usage amount increases.

  On the other hand, since the buffer member made of pulp mold can be manufactured from waste paper or the like, the manufacturing cost can be kept low. However, the generally used cushioning member made of pulp mold has a lower strength than the cushioning material made of cardboard sheet, and can be used only for an object to be packed of 20 kg or less at present. For this reason, when using a cushioning member made of pulp mold for heavy items to be packed, it is necessary to increase the thickness compared to those of general specifications, resulting in an increase in usage and corrugated cardboard The cost may be higher than that of a cushion member made of a sheet.

  An object of the present invention is to provide an impact cushioning member for packaging that is low in manufacturing cost and can withstand heavy objects.
