PURPOSE:To provide a cushioning material which protects an article to be packaged with a complicated shape at the time of packaging, and does not require a large storage place. CONSTITUTION:A cushioning material is equipped with a sealed container 2 of which the outer shape is a flat plate form, and a liquid 3 of a low freezing point which is sealed in the sealed container 2, and the sealed container 2 is formed of a flat member with flexibility. Also, an putting/discharging port (not shown in the drawing) for the liquid 3 of the low freezing point is provided on the sealed container 2. By this method, the production cost is reduced, and an impact from the outside is reduced by the flowing of the liquid of the low freezing point in the sealed container. |
