Description

  This invention relates to a paper cushioning material.

  Conventionally, the cushioning material of a relatively heavy transported material such as an automobile part or a housing building material has been used in combination with foamed plastic or the like because the cardboard alone has insufficient strength in terms of pressure resistance.

  For this reason, processing after use takes time, wastes time and labor, and various problems such as shortage of raw materials and price increase have become apparent.

Therefore, for reference, the patent documents of cushioning materials (cushion materials) filed so far will be introduced. (See Patent Documents 1 to 3.)
