[Problem to be solved by the invention] However, since styrofoam is made from petroleum, which is a finite natural resource, it is best to avoid using it as a packaging material, which will be discarded once the purpose of transportation is fulfilled. is desirable. In addition, from the perspective of measures to dispose of municipal waste, which is becoming increasingly serious, Styrofoam is bulky, increases transportation costs, is not suitable for landfilling, and when burned, generates high temperatures that can damage incinerators. Because I have
It is hoped that some kind of alternative product will emerge to replace this. On the other hand, stacked cardboard pieces are preferable because they are made from recyclable wood and have far fewer disposal issues than styrofoam, but they require a lot of labor to cut and stack the cardboard and are expensive. In addition to being economically disadvantageous, the buffering function is also insufficient. Therefore, the object of the present invention is to create a package that can be made efficiently and inexpensively using corrugated cardboard as a material, has a better cushioning function than conventional laminated blocks of corrugated cardboard pieces, and can be folded compactly for storage and transportation.
