On the other hand, the first folded bubble cushioning sheet 15b on the back side extends further upward than the upper edge of the five sheets (described above) such as the first folded bubble cushioning sheet 15a on the front side (the backside) In the state in which the first folded bubble cushioning sheet 15b is formed into a vertical flat surface), the portion is used as an adhesive folded portion 17.
An adhesive is attached to the inner surface of the folded portion 17 for bonding to form a belt-like adhesive attaching portion 18, and a protective sheet 19 is attached to the adhesive attaching portion 18.

Next, the manufacturing method of this buffer packaging material is demonstrated based on FIG.
As described above, the buffer packaging material is formed of three sheets (the first bubble buffer sheet 11, the second bubble buffer sheet 21, and the nonwoven fabric 31).
The rolls 111, 121, 131 of the sheets 11, 21, 31 are installed in a fixed manner in parallel.
Then, the sheets 11, 21, 31 are pulled out from the rolls 111, 121, 131 so as to overlap each other, and the triple sheets 11, 21, 31 are simultaneously bent by the triangular plate 150 and the slit device 155. , 6-fold.
Then, the hexagonal sheet is melted at predetermined intervals. That is, in a state where the hexagonal sheet is placed on the base 160, the high-temperature fusing member 162 is lowered to weld and cut the hexagonal sheet.
Thus, the cushioning packaging material (described above) is almost manufactured.

Next, the usage method and effect of this buffer packaging material will be described.
As shown in FIG. 6, an article B such as a bumper of an automobile is accommodated in this cushioning packaging material (this is described above). The article B is accommodated in the internal space of the buffer packaging material (that is, the internal space of the nonwoven fabric bag 30).
In a state where the article B is accommodated, the protective sheet 19 is removed and the adhesive folded portion 17 is folded back at the adhesive folded portion 17 of the first bubble cushion sheet bag body 10 (the first folded bubble cushioned sheet 15b on the back side). Then, the folded portion 17 for bonding is bonded (adhered) to the vicinity of the upper edge portion of the first folded bubble buffer sheet 15a on the front side by the adhesive attaching portion 18 (its adhesive).

When the article B such as a bumper is accommodated in the buffer packaging material, the article B is protected as follows.
This buffer packaging material has the 1st bubble buffer sheet bag body 10 and the 2nd bubble buffer sheet bag body 20, and the bubble buffer sheet is made into double. For this reason, compared with the case where the bubble buffer sheet is single, the article B is more reliably buffered.
In addition, since the cushion packaging material has the nonwoven fabric bag 30 on the innermost side, the article B such as a bumper is directly covered with the nonwoven fabric 31, and thus is directly covered with the bubble cushioning sheet. As compared with the above, the surface of the article B such as a bumper can be protected more softly.

Further, in this cushioning packaging material, the first folded bubble cushioning sheet 15a on the front side and the second folded bubble cushioning sheet 25a on the front side are other than the left and right side edges (blocking portions 53a and 53b). Are not coupled, and a gap is easily formed between the two. The same applies to the second folded bubble cushioning sheet 25a on the front side and the folded nonwoven fabric 35a on the front side. The same applies to the back side.
For this reason, a larger buffering function can be obtained for the article B to be accommodated.

  The above is merely an example of the present invention, and it is needless to say that the present invention can be implemented in variously modified forms based on the knowledge of those skilled in the art.

For example, instead of having two (double) bubble buffer sheet bags, you may have only one. On the contrary, you may have three (three) bubble buffer sheet bag bodies.
Moreover, the buffer packaging material of this invention can take not only a rectangular shape but a various shape.
