Fold it in two, and align the edges on the width side to form a four-layer film stack.

Next, both side edges a, a of the multilayer body are heat-sealed in a bulging gentle curve shape, and the folded portion b of the film F ₁ is also heat-sealed for shape retention. By heat-sealing each of the two multi-layer films F ₁ and F ₂ on the opposite side edges c of the double-folded portion b separately, the air-filled accommodating portions 3, 3 are overlapped on the front side and the back side. the opposite type setting, the communicating by the distance L between the two packing accommodating portions 3 and 3 of the film F ₁ clamshell portion b and the film F ₂ clamshell portion b ', the both filled housing part An article storage section 4 having an article insertion / removal opening 5 on the side of the edge c is formed between 3 and 3.

When heat-sealing one of the multilayer films F ₁ and F ₂ at the edge c, a well-known flat check valve 6 made of a plastic film is attached to the edge film c at the edge c. _By interposing between ₁ and F ₂ and performing heat sealing, the inside and outside of both filling and accommodating parts 3 and 3 are communicated with each other only through the air supply / discharge port 7 provided with the check valve 6. .

Further, in the embodiment, the both filling / accommodating portions 3 and 3 are located along the insertion direction of the article, and in a state where the communicating portions 10 and 10 are left at both ends, in this embodiment, one portion of each intermediate portion. Each of them is heat-sealed linearly by means of the seal part d, and two air compartment filling / accommodating parts 8, 8 are respectively formed in both the accommodating / accommodating parts 3, 3 by the sealing part d. A bifurcated branch seal is applied from the end of the insertion / removal opening 5 side, and a pocket-shaped pouch 9 is formed in the one communication part 10 by the branch seal part e, and the pouch 9 and two compartments are separated from each other. The filling / accommodating portions 8 and 8 are communicated with each other by two narrow gap flow paths 11 and 11 formed by unsealed portions, and a semi-arcuate seal is formed from the other end of the sealing portion d 1. The part f is connected to form the packaging bag 2 of the present invention. .

Then, the packaging bag 2 configured as described above is accommodated in the box from the opening / closing lid 1a of the packaging box 1 with the insertion / removal opening 5 side facing toward the four compartment filling / accommodating portions 8, 8, 8 and 8 are attached to the four inner peripheral surfaces of the packaging box 1, the outer surface of the insertion / removal edge of the packaging bag 2 is bonded 12 to the inner surface of the packaging box 1, and the protruding portion of the check valve 6 is attached to the packaging box 1. The cushioning packaging material according to the present invention is constructed by protruding from the opening edge of the opening / closing lid 1a.

Next, based on the above-mentioned embodiment, the usage state will be described together with the action and effect. First, the opening / closing lid 1a of the packaging box 1 is opened, the cushioning required article M is inserted from the insertion / removal opening 5 of the packaging bag 2 and stored in the storage section 4, and the air supply / discharge port section is provided via the check valve 6. When air is injected from 7, air is introduced into each of the compartment filling / accommodating sections 8 provided at four places through the communicating section consisting of the space L and one communicating section 10 which is not sealed, and the accommodating section The part 8 is inflated and brought into close contact with the inner peripheral surface of the packaging box 1, and the stored articles are buffer-protected in a suspended state.

At this time, since the storage parts 8 are provided in parallel along the storage direction of the articles and are evenly arranged in the front and rear and on both sides, the storage articles M are buffer materials. Since it is sufficiently and evenly held in the wound-wrapped state, the cushioning effect on the stored article is excellent, and the stored article does not leak out.

In addition, the packaging bag 2 in which the stored articles M are buffer-wrapped in this manner expands the filled air therein when the storage bag 2 is placed in a high temperature environment, so that the compartments 8 and 8 are filled. When the internal pressure increases until the formed plastic films F ₁ and F ₂ are about to burst, the narrow gap flow channels 11 and 11 of the pouch 9 that is separately formed in each compartment 8 are pushed. Since the air is introduced into the pouch by opening it, the abnormally high internal pressure in the container can be relieved, the container can be prevented from bursting, and the cushioning effect can be maintained.

Furthermore, since a semi-circular arc-shaped seal portion f is continuously provided at the end of the straight seal portion d provided on the packaging bag 2 on the side opposite to the insertion / extraction opening, the end of the seal portion d is formed. The full air pressure applied to the part is dispersed and relaxed by the seal part f and the packaging material is not broken from the end part of the seal part d.

Although the main embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and for example, the forming position and shape of the pouch 9 can be arbitrarily selected and set. The number of partition filling / accommodating portions 8 can be appropriately increased, that is, the purpose of the invention can be achieved, and various design changes can be made without departing from the spirit of the invention.
