At this time, the side edge portion 5 and the side edge portion 4 were each provided with a width of 5 mm to serve as a welding margin. Next, according to the dimensions of the precision electrical components to be packed, the sides are divided into regular squares with a side of 300 mm, and the borders 13 are heat-welded to substantially 16 rectangular air chambers 7. A strip-shaped synthetic resin film was formed. At this time, at least one non-welded portion was provided in the side portion 4 and the border portion 13 to form an air flow port 8, and the air chambers 7 were integrally connected through the air flow port 8.

An air inlet 3 is provided in at least one location of the air chamber 7, and the air inlet 3 is provided with a check valve 4. The air pressure in each chamber is expanded in accordance with the desired air pressure (3.5 Kpa / cm ² in this embodiment) by the air supplied from the air inlet 3. At this time, instead of the check valve 4 provided in parallel with the air inlet 3, the air inlet 3 after the air injection can be sealed by heat welding. When the four air chambers 7 at the lower end of the band-shaped synthetic resin film of the sixteen rectangular air chambers 7 in the present embodiment are bent inward, they become substantially right angles of 90 degrees. A notch 12 is formed as described above, and a notch edge 14 of the notch 12 is heat-welded to form a bottom 9 composed of four air chambers, as shown in FIG. A square frame having the bottom 9 is completed. The back surface of the precision electrical components packed by the cushioning effect of the bottom part 9 has a fear of increasing the frictional resistance due to the contact with the face and the cushioning effect by air and the risk of collapse or displacement due to the protection by the frame shape.
