An inexpensive universal air-cushioning material capable of stably packaging packaged bodies of different shapes and sizes with a simple structure and withstanding long-time transportation under severe conditions, wherein the side edge parts of two sheets of laminated square synthetic resin films of a same material forming the end parts of the upper and lower and right and left outer frames thereof are thermally fused to each other and the intermediate parts thereof are thermally fused to each other between the side edge parts arbitrarily according to the sizes and shapes of the packaged bodies to provide border parts divided into a plurality of parts. At least a pair of cutout parts are provided, symmetrically in the lateral direction, at any positions near the side edge parts of the border parts according to the sizes and shapes of the packaged bodies. At least one air flow port is formed at the border parts to form a plurality of air chambers communicating with each other so that a contact area between the air chambers and the packaged body or the inner wall of a carry container can be arbitrarily changed. Also, the entire parts of the air chambers are inflated by filling air into at least one of the air chambers through an air filling port, and the inside thereof is allowed to press against the packaged body and the outside thereof is allowed to press against the inner wall of the carry container.
