[0005]
Furthermore, since the cushion material for packaging made of polystyrene foam is bulky due to its large volume, the burden of transporting or storing the cushion material is not great, and it also causes problems when discarded. There is.
[0006]
The air cushion is generally bulky because the air cushion has a large volume because air is sealed inside the air cushion when the air cushion is manufactured. The air cushion is also transported or stored. The burden to manage is great.
[0007]
Therefore, for use by blowing air at the time of use, for example, a square-shaped heat-fusible plastic film is overlaid and its peripheral edge is heat-sealed, and the main body is linearly arranged at a plurality of positions in the left-right direction. Heat-sealed to form a wide air filling enclosure and at least one narrow air filling enclosure, and a check valve for filling and filling the air is provided at an appropriate position on the periphery of the body. There is a cushioning material for packaging in which air supplied from the check valve can be introduced into an air-filled enclosure through a ventilation gap (see Patent Document 1).
[0008]
In the known technique of this Patent Document 1, it is mainly used as a cushioning material for packing ice cream filling cones, and is not intended for packaging objects such as electronic devices. The product is not used by being wrapped in the packaging cushioning material, but the packaging cushioning material is expanded, and a plurality of the packaging cushioning materials are stacked and used.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail based on specific embodiments.
A cushioning material for packaging according to a first embodiment of the present invention is shown in FIGS. FIG. 1 is a schematic plan view of a cushioning material 1 for packaging. The packaging cushioning material 1 is formed in a state where two resin films are overlapped. As this resin film, it is preferable to use a resin film having high strength.
[0017]
The outer shape of the cushioning material 1 for packaging is formed in a rectangular shape, for example, a rectangular shape, and its outer peripheral edge portion is sealed by forming a heat sealing portion 2 by heat sealing, and a part of the heat sealing portion 2 is sealed. The air blowing member 3 is interposed.
[0018]
The air blowing member 3 has a check valve structure, and blows air from the outside of the packaging cushioning material 1 through the air blowing member 3 using, for example, a straw (not shown). However, since the blown air is configured not to blow from the air blowing member 3, the blown air can be maintained inside the cushioning material 1 for packaging.
[0019]
The cushioning material 1 for packaging has, for example, a bottom side air chamber 5a, a top side air chamber 5b, and a side surface of the article to be packaged by an adhesive seal portion 4 that is a partition seal portion that can be bent by reaching the heat seal portion. It is divided into a side air chamber 5c, a front side air chamber 5d, and a back side air chamber 5e.
[0020]
The adhesive seal portion 4 is bonded and bonded with an adhesive. As this adhesive, for example, a thermoplastic adhesive such as hot melt can be used, and the strength at which the adhesive seal portion 4 peels is preferably at least 5 kg.
[0021]
The adhesive seal portion 4 that divides each air chamber 5 of the bottom side air chamber 5a, the top side air chamber 5b, the side air chamber 5c, the front air chamber 5d, and the back air chamber 5e A part is formed with a gap as an air passage 6 for allowing air to flow through each of the air chambers 5.

As Production Example 1 of the packaging cushioning material 1, an adhesive is printed at a predetermined position of at least one of the two resin films 8a and 8b to be superimposed, that is, a position where the adhesive seal portions 4 and 4a are formed, Before the adhesive is dried, the two resin films 8a and 8b are overlapped to adhere the position where the adhesive is printed, and then the outside of the cushioning material 1 for packaging with the air blowing member 3 interposed therebetween. The peripheral portion is heat sealed to form the heat seal portion 2.
[0028]
As described above, by bonding the predetermined positions, that is, the positions of the adhesive seal portions 4 and 4a with the adhesive, only the heat seal portion 2 is sealed, and the number of the heat seal portions can be reduced. Therefore, since the shape of the electrode (not shown) for heat sealing can be simplified, the cost of manufacturing the electrode can be reduced, and a simple operation of printing the adhesive Since the predetermined position can be adhered, even a complicated shape can be adhered uniformly and accurately as a whole.
