<P>PROBLEM TO BE SOLVED: To provide a packing material which is easily transported and manufactured, and is formed with a shape for protecting a part hitting a corner of a packed material if gas or liquid is supplied to expand a gas housing part. <P>SOLUTION: The packing material 1 provided with a gas housing part for housing gas by heat-welding circumferential parts of two plastic films having heat weldability and flexibility includes a flat surface part 20 formed with a gas housing part for housing gas by heat-welding the plastic films at a linear heat welding part, and a folding part 30 formed by heat-welding at a linear heat-welding part 42 orthogonal to or parallel with a heat-welding part 41 of the flat surface part 20 of the plastic film and the heat-welding part 41, and a gas housing part 52 of the folding part 30 is hit to a corner (a first corner) formed by one side where two surfaces of the packed material intersect. <P>COPYRIGHT: (C)2013,JPO&INPIT |
