PROBLEM TO BE SOLVED : To solve the problem in which, in a next generation transportation such as a drone and the like, a conventional cushioning material whose purpose is only preservation of objects, resource saving and reduction in waste is not sufficient, and a function actively reducing weight of a transportation article is required as well.MEANS FOR SOLVING THE PROBLEM : In a cushioning material constituted by filling air in a thin resin film, helium is filled and sealed in place of air. The film for the cushioning material is a lightweight material such as polyethylene, polypropylene, nylon and the like. As helium is becoming one of rare resources, so the cushioning material is premised on reuse. In actual transportation, in order to collect leakage of helium from the cushioning material, an upper part of a transportation article is covered by a gas collecting cover and the like separately. Thereby, it is effective in preventing lowering of buoyancy when gas leakage occurs and in preventing oxidation of the transportation article.SELECTED DRAWING : Figure 2COPYRIGHT : (C)2018, JPO&INPIT
