Problems solved by technology

Common inflatable liners are composed of long strips of air columns. When using this kind of packaging bag to pack glass bottles such as soy sauce bottles, beverage bottles, and beer bottles, the direction of the air columns is consistent with the height of the bottle. When one or several air columns are broken, the bottle cannot be well protected, resulting in damage to the bottle

Embodiment 1

[0040] Such as Figure 1-Figure 4 As shown, a pressure-resistant inflatable packaging body includes: two layers of inflatable packaging outer membranes, the top, bottom and left ends of the two-layer inflatable packaging outer membranes pass through the heat-sealing line 12, the heat-sealing line 13 and the heat-sealing line 14 respectively. Bonded together to form a body 1, a number of parallel heat-sealing lines 2 are provided in the longitudinal direction of the body 1, and each heat-sealing line 2 divides the body 1 into several strip-shaped air columns 3, and the top of the air column 3 is connected to the The heat-sealing line 12 is separated by a certain distance, and the bottom of the air column 3 is connected with the heat-sealing line 13 . A one-way air valve 4 corresponding to each air column is provided on the top of the air column 3, and the one-way air valve 4 is fixed on the body 1 through a heat-sealing line 15. Inflating passages 6 corresponding to the one-wa...

Embodiment 2

[0050] Such as Figure 6-Figure 9 As shown, the structure of the pressure-resistant inflatable package provided in this embodiment is basically the same as that of Embodiment 1, the difference is that a certain number of air columns 3 are not inflated from the side of the body 1 glued and sealed, After the main body 1 is inflated to form a hollow columnar cavity, the uninflated air column set A is stuffed into the hollow columnar cavity to form an inner bag, which is convenient for packaging and provides better protection for the packaging.

[0051] In this embodiment, a certain number of air columns 3 are not inflated from the adhesively sealed side of the body 1 , which is achieved by cutting off the heat-sealing line 16 to cut off the inflation channel 6 . The length of the uninflated air column does not exceed the length of the inflated air column to prevent the inner bag from leaking from the other end of the hollow columnar cavity.

Embodiment 3

[0053] Such as Figure 10-Figure 12 As shown, the structure of a pressure-resistant inflatable package provided by this embodiment is basically the same as that of Embodiment 1, the difference is that both sides of the body 1 in the transverse direction are not glued and sealed, away from the one-way air valve 4 The end of the nearest bending line 5-1 of the air inlet uses a continuous heat-sealing line 10 to isolate this part of the air column into upper and lower parts, so that part of the air column 3-4 on the heat-sealing line can be inflated, and the lower part of the heat-sealing line can be inflated. Some of them cannot be inflated, and some air columns 3-4 on the heat-sealing line after inflation constitute the inflatable protective surfaces of the ports at both ends of the hollow columnar cavity. In this way, the surroundings of the entire packaging body are protected by the air column, which can achieve a better protection effect.

[0054] In other embodiments, it i...

Abstract

The invention discloses a compressive resistance type gas filling packaging body which comprises two layers of gas filling packaging body outer films; the peripheries of the two layers of gas filling packaging body outer films are mutually connected to form a body; a plurality of parallel heat sealing lines are arranged on the body in the longitudinal direction and divide the body into a plurality of strip gas columns; and a one-way gas valve is arranged at one end of each gas column. The compressive resistance type gas filling packaging body is characterized in that at least two rows of bend lines are arranged on the body in the transverse direction and divide each gas column into at least three small gas column sections, and the body is folded in half in the longitudinal direction to enable the two ends of each gas column to be adhered to each other; when gas is fully filled in the gas columns, each small gas column section bulges to form a hollow cylindrical cavity, and the axial direction of each hollow cylindrical cavity is perpendicular to the running direction of each gas column; and after a glass bottle is put into the gas filling packaging body, the height direction of a glass bottle body is perpendicular to the running direction of each gas column, and the gas columns resist compression, are difficultly broken and can have well protection effect to the glass bottle although several gas columns are broken without influencing the use.

Description

technical field [0001] The invention relates to the technical field of inflatable packaging bags, in particular to a pressure-resistant inflatable packaging body. Background technique [0002] Before the commodity enters the final consumption link, it usually needs to go through warehousing, transportation, sales and other links. In order to prevent the items from being impacted during storage and transportation, some protective materials, such as waste paper and plastics, are usually filled in the gaps after the items are packed. Although this can play a certain degree of cushioning, due to the uneven filling of these materials, it is difficult to provide uniform cushioning force to the item in all directions, and these protective materials are disposable and will not be reused. Therefore, it will cause environmental pollution. Especially for precision instruments and equipment, it is not suitable to use this packaging method. [0003] In addition, there is also a tradit...
