[0029] See also Figure 1 Inflatable packaging bags are packaging materials that fill the packaging space by filling gas or liquid. They are usually made of plastic materials or composite materials, and can be filled with gas or liquid through inflating equipment or manual inflation. Inflatable packaging bags have advantages in protecting goods from squeezing, vibration and collision, and can be used to protect fragile items, electronic products, glass products, etc. However, inflatable packaging bags have a certain risk of leakage. Due to the limitations of materials and production processes, this type of packaging bag may leak due to material damage, loose sealing, etc. Based on this, please refer to Figure 2 , Figure 3 , the present application provides a shockproof and dropproof cushioning inflatable bag, comprising a bag 1 for packaging and a sealing member 2 connected to both sides of the bag 1;

[0030] The bag 1 comprises an outer frame 12, the outer side of the outer frame 12 is covered with a covering layer 11, and the covering layer 11 is provided with vents 14 on both sides of the outer frame 12;

[0031] An inner cavity 13 is provided on the inner side of the outer frame 12 covered by the covering layer 11, and the inner ends of the inner cavity 13 are connected to the vents 14;

[0032] The sealing member 2 includes a card frame 21 , which is disposed on one side of the cover layer 11 and is adapted to the vent 14 .

[0033] The design of the shockproof and dropproof cushioning air bag is mainly divided into two parts: the bag 1 and the seal 2. The bag 1 is the main part used for packaging, and its structure includes an outer frame 12 and a covering layer 11. The outer frame 12 is the skeleton of the bag 1, providing support and stability. The outer side of the outer frame 12 is covered with a covering layer 11, and the function of the covering layer 11 is to increase the protective performance of the packaging bag. Vents 14 are provided on both sides of the covering layer 11 for filling gas or liquid to fill the packaging space.

[0034] An inner cavity 13 is provided on the inner side of the outer frame 12 covered by the covering layer 11, and both inner ends of the inner cavity 13 are connected to the vents 14, so as to ensure that when the inner cavity 13 is inflated, the gas or liquid can evenly fill the entire bag 1, providing a uniform cushioning effect.

[0035] The other part is the sealing member 2, which includes a card frame 21. The card frame 21 is arranged on one side of the covering layer 11 and is adapted to the vent 14, so that the card frame 21 can be tightly connected to the bag 1 and the vent 14 can be easily used. Through the design of the card frame 21, when the inflatable bag is inflated and used, the stability of the bag 1 can be better maintained to prevent accidental falling off or displacement.

[0036] The outer frame 12 is an important component of the shockproof and dropproof cushioning air bag, and acts as a skeleton. In order to combine with the covering layer to cover the covering layer, it can generally be made of plastic materials such as polyethylene (PE), polypropylene (PP), and polyester (PET). These materials have good toughness and durability, can effectively resist external pressure and impact, and provide stable structural support for the bag 1;

[0037] Foam materials, such as polyethylene foam or polyurethane foam, can also be used. Foam materials have excellent shock absorption and cushioning properties, and can effectively reduce the impact of external shocks on packaged items;

[0038] Paper materials such as corrugated cardboard or acrylic cardboard can also be used. These materials have certain strength and rigidity, can provide appropriate support for the inflatable bag, and are environmentally friendly.

[0039] Different materials can be selected according to needs and costs. For example, foam materials can be used to wrap valuable items, and paper materials can be used for support to meet the needs of subsequent recycling.

[0040] See also Figure 4 and Figure 5 as well as Figure 6Through holes 23 are provided on both sides of the card frame 21 , and the through holes 23 are adapted to the vents 14 . Both sides of the card frame 21 are sealed and fitted with the covering layer 11 at the through holes 23 .

[0041] Through holes 23 are provided on both sides of the card frame 21, which are adapted to the vents 14 for smooth filling of gas or liquid. At the through holes 23, both sides of the card frame 21 are sealed and attached to the cover layer 11 to ensure the sealing performance of the inflatable bag. The bonding method can be glue coating to improve the bonding performance;

[0042] The top and the bottom of the card frame 21 are both provided with strip grooves 22 arranged at equal distances, and a sealing film is provided at the strip grooves 22 .

[0043] A sealing film is provided at the strip groove 22. Through the combination of the strip groove 22 and the sealing film, the pressure bearing capacity of the card frame 21 can be enhanced, the risk of damage to the coating layer can be reduced, and a better sealing effect can be provided during the use of the inflatable bag.

[0044] The inner side of the card frame 21 is provided with a receiving cavity 24, the inner side of the receiving cavity 24 is penetrated by the through hole 23, and a sealing area is formed by a sealing film. Such a design can ensure that the sealing area is airtight to prevent gas or liquid leakage, and at the same time ensure uniform filling and flow of gas or liquid inside the inflatable bag.

[0045] The outer side of the covering layer 11 is coated with a puncture-proof coating 16 , and N soft strips 15 are arranged at the puncture-proof coating 16 to protect the covering layer 11 .

[0046] The function of the coating is to increase the puncture resistance of the covering layer 11 to a certain extent, effectively protect the internal inflatable bag from being damaged by external sharp objects, and improve the safety and durability of the packaging.

[0047] The plurality of soft strips 15 are arranged at equal intervals, and the outer sides of the soft strips 15 are arranged in an arc shape, so as to mitigate the compression of the cover layer 11 by the impact.

[0048] A plurality of soft strips 15 are arranged at the anti-puncture coating 16, and the function of these soft strips 15 is to provide additional protection for the cover layer 11. These soft strips 15 are arranged at equal intervals, covering the entire surface, and can disperse external impact force, reduce direct pressure on the cover layer 11, and improve the impact resistance of the cover layer 11.

[0049] The outer side of the soft strip 15 is arranged in an arc shape. This design can reduce the impact on the covering layer 11, prevent sharp objects from directly piercing, provide a more uniform protection surface, and reduce the risk of piercing.

[0050] The puncture-resistant coating 16 is a specially designed coating that aims to improve the puncture resistance of the product surface and prevent the product from being punctured or damaged by sharp objects. In the industrial and packaging fields, there are many types of puncture-resistant coating 16 to choose from, such as polyurethane coating, polyethylene coating, etc.

[0051] Furthermore, the coating can enhance the performance and function of the bag 1. For example, from a functional perspective, a waterproof coating, an anti-fouling coating, an anti-static coating, etc. can be used. These functional coatings can give the inflatable bag additional properties, such as moisture resistance, anti-fouling and anti-static, and improve the quality and reliability of the packaging.
