That is, the cushioning material a is composed of three films.
e, e, and e are used to form a buffer block f having a three-phase structure that defines the air chamber b and the urethane chamber d. Further, the cushioning material a is formed by integrally coupling a large number of cushioning blocks f according to use conditions, with the cushioning block f as one unit. The air chamber b, the urethane chamber d, and the buffer block f defined by the film e are sealed by thermocompression bonding.

The film e on the surface side of the urethane chamber d
Is provided with a plurality of air holes, and adjusts the pressure change when the air in the air chamber b expands or contracts due to temperature, atmospheric pressure, etc., so that a constant cushioning property is always exhibited.

Therefore, the cushioning material a has the following advantages by combining the urethane chamber d using the urethane foam c having an excellent cushioning property and the air chamber b filled with air. there were. For example, the urethane foam c, which has a constant cushioning property even in an environment in which the temperature and atmospheric pressure fluctuate drastically, such as the cargo compartment of an aircraft, that is, is not affected by changes in temperature and atmospheric pressure, is approximately 2% of the polystyrene foam.
By filling with air, which has an extremely high impact absorption of double, it fits various shaped articles. It is robust and can withstand repeated use over a long period of time.

However, although the cushioning material a has various advantages as described above, the film e forming the air chamber b and the cushioning block f is made of brushed nylon cloth, polyethylene resin (L). -LDPE) and drawn nylon have a multi-layer structure in which materials made of petroleum-based raw materials are laminated, and since urethane foam c is used as a cushioning material, it only has a problem of high cost. Moreover, there was a problem that the environmental load at the time of disposal was large.

That is, the environmental load at the time of disposal means that the film e and the urethane foam c made of the above-mentioned materials have poor decomposability at the time of disposal, and when incinerated, a cyan gas is generated. Since the incinerated ash after incineration contains dioxin and the like, which have become a problem in recent years, it has a great influence on the environment (which is against environmental protection).
