[0008] Preferably, the first waterproof layer is a polyurethane waterproof coating waterproof layer, and the second waterproof layer is a polyvinyl chloride waterproof layer.

[0009] Preferably, the anti-wear layer is a wear-resistant coating glue anti-wear layer.

[0010] Preferably, the sub-bag is a top-opening structure, and the top opening of the sub-bag is sealed and connected by a zipper.

[0011] Preferably, the two handles are fixedly connected by snaps.

[0012] The waterproof packaging bag of the utility model has the following advantages:

[0013] 1. The utility model sets the front and rear side walls of the main bag into a wavy structure, which makes it easy to unfold and fold the main bag. When the main bag is unfolded, the interior of the main bag is exposed, which is convenient for users to take items. Through the setting of the secondary bag, it is convenient to place and store items that need to be sealed in the secondary bag, thereby realizing classified storage of items and improving the practicality of the packaging bag.

[0014] 2. By setting the front and rear side walls of the main bag as a wavy structure, it is convenient to unfold and fold the main bag. When the main bag is unfolded, the inside of the main bag is exposed, which is convenient for users to take items. With the cooperation of the two handles, it is easy to take the packaging bag.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0024] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a waterproof packaging bag of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, a waterproof packaging bag of the utility model comprises an expandable main bag 1, and sealable sub-bags 2 are arranged on both sides of the main bag 1. The main bag 1 and the sub-bag 2 are respectively composed of a first waterproof layer 5, an imitation kraft paper layer 6, a second waterproof layer 7 and an anti-wear layer 8 from the inside to the outside. The first waterproof layer 5 is a polyurethane waterproof coating waterproof layer, and the second waterproof layer 7 is a polyvinyl chloride waterproof layer. The first waterproof layer 5 and the second waterproof layer 7 are provided to greatly improve the waterproof effect of the packaging bag. The anti-wear layer 8 is a wear-resistant coating glue anti-wear layer. The provision of the anti-wear layer 8 can improve the wear resistance of the packaging bag during use, thereby avoiding the packaging bag from being damaged due to wear after a period of use, and improving the service life of the packaging bag. The top side walls of the two sub-bags 2 are provided with handles 3.

[0027] The main bag 1 is a top-opening structure, and the front and rear side walls of the main bag 1 are a wavy structure. By setting the front and rear side walls of the main bag 1 as a wavy structure, it is convenient to unfold and fold the main bag 1. When the main bag 1 is unfolded, the inside of the main bag 1 is exposed, which is convenient for users to take items. The auxiliary bag 2 is a top-opening structure, and the top opening of the auxiliary bag 2 is sealed and connected by a zipper 4. Through the setting of the zipper 4, it is convenient to place the items that need to be sealed in the auxiliary bag 2 for storage, thereby realizing the classified storage of items and improving the practicality of the packaging bag. The two handles 3 are fixedly connected by snaps. Through the setting of the two handles 3, when the two handles 3 are combined and fixedly connected by snaps, the two auxiliary bags 2 will move closer to each other, thereby reducing the area of ​​the packaging bag, which is convenient for taking the packaging bag. When the two handles 3 are separated, the two auxiliary bags 2 will move away from each other, so that the main bag 1 is unfolded, which is convenient for taking and placing items.

[0028] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
