Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The technical solution of the present invention will be described in detail with reference to the following examples.
The double-layer packaging bag with the inflatable sealing structure as shown in fig. 1-2 comprises an inner bag 10 and an outer bag 11, wherein the inner bag 10 is embedded inside the outer bag 11, and the two bags are bonded at an opening to form a bonding part 12, and the bonding part 12 can be bonded by hot pressing or other bonding methods such as gluing; thus, the two separate bag body structures are combined to form an inner-outer nested double-layer packaging bag structure with a storage opening, and goods 3 to be transported are placed in the inner bag 10 through the storage opening; in the double-layer packaging bag, a cavity structure is formed between the inner bag 10 and the outer bag 11 as a gas bag cavity 13.
