Problems solved by technology

[0005] Aiming at the problem that existing inflatable bag packaging products have insufficient anti-vibration ability for relatively high impact, the purpose of the present invention is to improve the existing inflatable bag and provide a double-buffer inflatable packaging bag. The impact buffer in one direction has a double buffer structure, which can better absorb impact energy and improve the shock absorption capacity of this part

Embodiment 1

[0038] This embodiment is used as a best implementation mode, combining figure 1 and figure 2 As shown, the double cushioning inflatable packaging bag, the main part is an outer bag 100 formed by an inflatable plastic film, which is provided with an article accommodation cavity and one end is an article insertion port 400. The inflatable plastic film has multiple such as Figure 4 In the strip-shaped inflatable chamber 13 structure shown, each strip-shaped inflatable chamber 13 communicates with the main inflation channel 7 through a one-way check valve; an auxiliary film 200 is also lined inside the article accommodation chamber of the outer bag 100 to form an inner pocket structure, The edge of the auxiliary film 200 is connected with the edge of the article inlet 400 of the outer bag, and the bottom of the auxiliary film 200 has a certain distance from the bottom of the outer bag 100, so that the outer bag 100 is inflated as if figure 2 Its bottom is shown not in contact...

Embodiment 2

[0057] The difference from Example 1 is that no side openings are reserved on the two side edges of the outer bag near the bottom of the bag, and all of them are heat-sealed twice to form an outer bag closed on three sides, such as Figure 6 As shown, what this embodiment forms is that there is a suspended lining auxiliary film 200 inside the outer layer bag 100, and the upper part is an article insertion port 400. The structure is simple, and the impact energy for the bottom of the bag is from the bottom along the outer layer bag 100 to Items are delivered in the direction of the mouth, and then the goods are delivered through the lining auxiliary film 200. Although the cushioning effect is slightly lower than that of embodiment 1, it is still much better than the protective effect of directly packaging the goods with only the outer bag 100. The air columns formed by the inflatable chamber 13 are arranged vertically to improve the vertical pressure bearing capacity.

Embodiment 3

[0059] Such as Figure 7 , the air chamber 13 of the outer bag 100, that is, the direction of the air column, is set horizontally. This way is used in commodities such as Figure 7 When placed in the manner shown, the rigidity of the side wall of the bag is slightly lower at the same specifications of the inflatable chamber and the inflation pressure, and it is easy to bend under the pressure of the product, and the impact resistance is reduced, and the protection effect on the impact of the bottom is lower than that of the bag. figure 2 and Figure 6 However, it is still much better than the method without using the auxiliary film 200 in the air. The item insertion port 400 is used for inserting items.

Abstract

The invention discloses a double-buffering inflatable packaging bag and a manufacturing method thereof. The double-buffering inflatable packaging bag comprises an outer bag, the outer bag is formed by an inflatable plastic clamping film and provided with a goods accommodating cavity, and one end of the outer bag is a goods inlet. The inflatable plastic clamping film is provided with multiple strip inflation chambers (13), and each strip inflation chamber (13) is communicated with a main inflation channel (7) through a one-way check valve. An inner bag structure composed of an auxiliary film is lined inside the goods accommodating cavity of the outer bag, and the edge of the auxiliary film is connected together with the edge of the goods inlet of the outer bag; and a certain distance between the bottom of the auxiliary film and the bottom of the outer bag is reserved, so that the bottom of the outer bag does not contact with the bottom of the auxiliary film after the outer bag is inflated. The inflatable packaging bag is made of five layers of plastic films by means of heat sealing and folding, is uninflated and can be folded optionally during production, storage and transportation, and is small in space occupation and reusable; and multiple-buffering effect can be formed locally so as to meet requirement on high local shock resistance of goods.

Description

technical field [0001] The invention relates to an inflatable packaging bag, which is an inflatable bag packaging material used for moisture-proof, shock-proof, extrusion-proof and impact-proof of goods. After being inflated, it can be used as filling material for article packaging, and can also be used as six-sided protective pad inside the article packing box, and it can also be used as the outer packing bag of the article to directly make the retail packaging of the product. Background technique [0002] Many commodities, especially fragile products such as electronic products and glass products, need to use expanded polystyrene, polyethylene bubble pads, etc. between the packing box and the commodity during storage and transportation, or directly pack the commodity with foam materials, so as to Achieve shockproof, anti-extrusion, anti-shock effects, and prevent damage to goods during storage and transportation. Traditional expanded polystyrene (EPS) and polyethylene foa...
