[0002] Paper-plastic bags are composite bags that combine paper and plastic. Typically, they consist of an outer layer of paper and an inner layer of plastic. The paper layer provides strength and texture, while the plastic layer adds water resistance and durability. This design makes paper-plastic bags suitable for packaging that requires strength and moisture resistance, such as food, pharmaceuticals, and cosmetics. Combining the environmental friendliness of paper with the practicality of plastic, paper-plastic bags offer both functional and environmentally friendly packaging options.

[0003] The prior art has the following defects or problems: The prior art announcement number is: CN219619801U discloses a moisture-proof paper-plastic bag with a partition, including a paper-plastic bag main body, two first sub-buttons are fixedly installed on the outer walls on both sides of the paper-plastic bag main body, and first sealing strips are fixedly installed on the inner walls on both sides of the paper-plastic bag main body. The two first sealing strips are sealed and snap-fitted together, and a dividing strip is provided inside the paper-plastic bag main body. The dividing strip is fixedly connected to the bottom inner wall and both side inner walls of the paper-plastic bag main body, and two second sub-buttons are fixedly installed on the outer walls on both sides of the dividing strip.

[0004] During use, the above-mentioned equipment is provided with a detachable lifting strap, which can facilitate the lifting and carrying of the paper-plastic bag, making it easy to use. When the lifting strap is installed externally, it can also cover the sealing part of the paper-plastic bag to avoid contact with external water sources, ensuring the cleanliness of the sealing part. At the same time, a drying bag is also provided inside to absorb moisture inside the paper-plastic bag to prevent internal items from getting damp.

[0005] In actual use, the above-mentioned content has a complex structure, troublesome assembly, and is inconvenient to produce. The single-layer paper-plastic bag has limited waterproof effect and does not have the trend of DIY packaging products in existing life. The novelty is poor. Therefore, a moisture-proof paper-plastic bag with a partition is proposed.

[0006] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

[0009] As a preferred technical solution of the present invention, a side connecting layer is symmetrically fixedly connected between the two second sealing strips, and both sides of the partition layer are fixedly connected to the two side connecting layers respectively.

[0010] As a preferred technical solution of the present invention, an elastic layer is symmetrically and fixedly connected to the outside of the waterproof layer outer bag.

[0011] As a preferred technical solution of the present invention, the interior of the waterproof layer outer bag is symmetrically provided with mounting grooves, and the inner wall of each mounting groove is fixedly connected to a sub-button.

[0012] As a preferred technical solution of the present invention, the outside of the inner connecting layer is symmetrically fixedly connected with female snap buttons, and each of the female snap buttons is snap-connected with the corresponding sub-button.

[0013] As a preferred technical solution of the present invention, placement grooves are symmetrically provided inside the outer bag of the waterproof layer, and a drying bag is bonded to the inner wall of each placement groove.

[0014] As a preferred technical solution of the present invention, buckle grooves are provided inside the two inner connecting layers.

[0015] Compared with the prior art, the present invention provides a moisture-proof paper-plastic bag with a barrier layer, which has the following beneficial effects:

[0016] 1. A moisture-proof paper-plastic bag with a barrier layer, which is provided with a waterproof layer outer bag, an inner connecting layer, a barrier layer, a sub-button and a female snap button. The inner connecting layer is placed in the waterproof layer outer bag, and the two inner connecting layers are integrally formed and bonded with the two side connecting layers and the barrier layer to form two independent bag inner spaces for separate storage. The waterproof layer outer bag cooperates with the two elastic layers to form an outer waterproof layer. The elastic rebound effect of the elastic layer can be used to wrap the items in the bag space and waterproof the bag. The female snap button on the outside of each inner connecting layer is engaged with the sub-button inside the waterproof layer outer bag to connect the outer layer and the inner layer, forming a quickly detachable multi-layer structure, which is both waterproof and durable. The outer layer can be replaced and can be customized according to needs to improve novelty.
