As a conventional cushioning material, a foamed plastic such as styrene foam is widely used. The foamed plastic is a material having an excellent cushioning function for protecting the equipment, and can be easily molded according to the shape of various equipment, and has an advantage that the packing efficiency in the packaging material can be increased.

[0004]

However, although the foamed plastic itself has extremely excellent characteristics, it has various problems in the treatment after being used as a cushioning material in recent years. For example, the collection route has not been developed, so it is thrown away as household waste, which is a big social problem. Along with this, it takes a lot of time to handle at the time of collection and the collection cost becomes high. Moreover, since high energy is required for incineration and disposal, it is necessary to install an incinerator. In addition, since the cushioning material made of foamed plastic itself is extremely bulky, it has drawbacks of low transportation efficiency, high transportation cost, and a large storage space. For this reason, in the industry, a cushioning material having an excellent cushioning function and a simple structure has been widely demanded as a substitute for the foamed plastic.
