Please refer to FIG. 1 , an embodiment of the present invention provides a cushioning packaging structure with different shrinkage rates. Specifically, as shown in FIG. 6 , after the cushioning packaging structure of this embodiment is opened, its internal space can be planned to accommodate a flat-shaped product (not shown), such as a notebook computer or a tablet computer. That is to say, the cushioning packaging structure of this embodiment can be used as a protective bag for a notebook computer, so that the six planes of the notebook computer are properly protected during the transportation of the notebook computer.

Firstly, the cushioning packaging structure of this embodiment has a wall-shaped cushioning body 20W, and three walls bent into a U shape are the first cushioning wall 20A, the second cushioning wall 20C, and the transfer buffering wall 20B. In addition, at least one air column is added. In this embodiment, two first air columns 10 are used, and then bent into a U shape to protect the other three surfaces, that is, to surround the front end of the U-shaped wall-shaped buffer body 20W. Opening with side openings. Thereby, the present invention can provide comprehensive protection for flat products during transportation.

Wherein the first air column 10 has a transverse section 11 extending along the first direction, that is, the X-axis direction as shown in Figure 1, and two lateral sections 12 are bent along the second direction by the two ends of the transverse section 11 , that is, the Y-axis direction as shown in Figure 1. The wall-shaped buffer body 20W is formed by connecting a plurality of second air columns 20 in parallel, and these second air columns 20 extend along the second direction between the first buffer wall 20A and the second buffer wall 20C, that is, as The Y-axis direction in FIG. 1 may also be referred to as the longitudinal direction of the second air column 20 . The second air column 20 extends along the third direction at the transfer buffer wall 20C, that is, the Z-axis direction as shown in FIG. 1 . The bend of the second gas column 20 may form a point-shaped or short-line welded portion, such as the welded portion 22 in FIG. 1 , and the two sides of the bend can still communicate with each other. The bend of the first air column 10 also has a similar structure.

Referring to FIG. 2 to FIG. 4 , the first buffer wall 20A of the wall-shaped buffer body 20W is taken as an example for illustration. FIG. 2 is a cross-sectional view showing that the first buffer wall 20A and the first air column 10 are flat in an uninflated state. Fig. 3 shows the front view of the first buffer wall 20A in the uninflated state, which is also flat. The small volume of the wall-shaped buffer body 20W in the uninflated state is beneficial for storage, and it will be inflated again when it is to be packaged, as shown in Fig. 4 . As shown in FIG. 3 , the original width of each second air column 20 is L when it is not inflated.

In other words, the total width of the wall-shaped buffer body 20W in the uninflated state along the direction perpendicular to the second direction (Y-axis direction) is 1.57 times the length of the transverse section 11 of the first air column 10 . Assuming that the width of the weld strip (S11, see FIG. 2) between the second air column 20 is not calculated first, the shrinkage rate of the first buffer wall 20A along the first direction (X-axis direction) after the inflated state is 1/ 1.57, which is about 0.637.

In addition, the first air column 10 can be regarded as not shrinking along the first direction (X-axis direction) in the uninflated state and the inflated state, and the shrinkage rate is 0. Therefore, in the cushioning packaging structure of this embodiment, in the uninflated state and the inflated state, the front end is opened, and the first air column 10 and the plurality of second air columns 20 along the first direction (X-axis direction) have different characteristics. of shrinkage. Assuming that two pieces of cushioning packaging materials are formed into a linear weld line according to the general thermal welding method, after inflation, the first buffer wall 20A with a larger shrinkage rate will pull the first air column 10 with a smaller shrinkage rate.

And preferably, the welding point D is located at the end of the welding strips S21, S22 of two adjacent second gas columns 20 close to the gas-filling channel H. This advantage lies in Therefore, the inflated end of the second air column 20 is adjacent to the first air column 10 , which can produce a better cushioning and protection effect. The welding point D should not fall inside or outside the inflatable channel H, so as to avoid an uninflated portion between the first air column 10 and the second air column 20 . On the other hand, also prevent the welding point D from blocking the inflation channel H. Furthermore, the wrinkled end flap 25 after inflation can also be covered under the side flap 13 of the first air column 10, and the exposed part is the straight side flap 13, which is more beautiful.
