Hidden hand-held structures 8 are arranged on both sides of the packaging bag body 1. The packaging bag body 1 is convenient for storing items. The Velcro adhesive strip sealing structure The structure 2 is convenient for moisture-proof sealing of the opening on the upper end surface of the packaging bag body 1, and the first rubber sealing block 3 and the second rubber sealing block 4 are convenient for realizing moisture-proof sealing at the opening on the upper end surface of the packaging bag body 1 by squeezing and embedding with each other. The first convex strip 5 and the first groove 6 facilitate the first rubber sealing block 3 and the second rubber sealing block 4 to fit together more tightly, so that the sealing effect is better. The Velcro 7 is convenient for reinforcing the first rubber sealing block 3 and the second rubber sealing block 4 that are fitted together to prevent the first rubber sealing block 3 and the second rubber sealing block 4 that are tightly fitted from being forced to separate due to accidental external forces such as scratches. The hidden hand-held structure 8 is convenient for carrying, but can be hidden for storage, which is practical and not cumbersome.

[0026] Further, if Figure 4 As shown, the upper and lower surfaces of the first ridge 5 are provided with second ridges 9, and the upper and lower inner walls of the first groove 6 are provided with second grooves 10 adapted to the second ridges 9. The second ridges 9 and the second grooves 10 facilitate better engagement of the first rubber sealing block 3 and the second rubber sealing block 4 that are tightly fitted together, and will not slip easily.

[0027] Further, if Figure 3 and Figure 4 As shown, the Velcro 7 includes a connecting layer 11, a first hook surface 12 arranged at one end of the inner side of the connecting layer 11, a second hook surface 13 arranged at the other end of the inner side of the connecting layer 11, a first fur surface 14 arranged on the outer side of the first rubber sealing block 3, and a second fur surface 15 arranged on the outer side of the second rubber sealing block 4. The connecting layer 11 is convenient for supporting and fixing the first hook surface 12 and the second hook surface 13. The first hook surface 12, the second hook surface 13, the first fur surface 14 and the second fur surface 15 facilitate the Velcro 7 to be adhered to the outer surfaces of the first rubber sealing block 3 and the second rubber sealing block 4, and the first rubber sealing block 3 and the second rubber sealing block 4 are tightened again.

[0028] Further, if Figure 4 As shown, one end of the connecting layer 11 is fixedly connected to the first rubber sealing block 3 below the first rough surface 14 , so that one end of the connecting layer 11 is fixedly connected to the first rubber sealing block 3 .

[0029] Further, if Figure 4 As shown, the first hook surface 12 and the first fur surface 14 are folded and bonded together accordingly, and the second hook surface 13 and the second fur surface 15 are folded and bonded together accordingly.

[0030] Further, if Figure 1 , Figure 2 as well as Figure 6 As shown, the hidden carrying structure 8 includes a hollow storage strip 16 symmetrically arranged on the side of the packaging bag body 1, a connecting card strip 17 embedded in the hollow storage strip 16, and a carrying strip 18 arranged on the upper end surface of the two connecting card strips 17. The hollow storage strip 16 is convenient for storing the connecting card strip 17, and the connecting card strip 17 is convenient for connecting and fixing the carrying strip 18. The carrying strip 18 allows the user to carry the paper-plastic composite packaging bag.

[0031] Further, if Figure 1 and Figure 5As shown, the packaging bag body 1 is composed of a paper layer 19, a waterproof layer 20 and a woven layer 21. A plurality of folding grooves 22 are provided on the outer surface of the packaging bag body 1. The paper layer 19 makes the bag have a better texture and is recyclable without polluting the environment. The waterproof layer 20 improves the moisture-proof effect of the bag. The folding grooves 22 facilitate folding and storage of the bag when not in use.

[0032] Further, if Figure 6 As shown, a plurality of anti-skid grooves 23 are provided on the outside of the carrying strip 18, and the corners of the packaging bag body 1 are all arranged in an arc shape to reduce the wear on the corners of the packaging bag body 1. The anti-skid grooves 23 can prevent the user from slipping and falling off when carrying the bag.

[0033] like Figure 1-Figure 6 As shown, the principle of the moisture-proof paper-plastic composite packaging bag provided in this embodiment is as follows: when using the device, the bagging body 1 should be stretched out through the folding groove 22, and then the required items should be filled in the packaging bag body 1, and then the first rubber sealing block 3 and the second rubber sealing block 4 can be pressed to make them tightly snap together. At this time, it is necessary to ensure that the first convex strip 5 on the first rubber seal 3 is tightly snapped into the first groove 6 on the second rubber sealing block, and it is also necessary to ensure that the second convex strip 9 on the first convex strip 5 is tightly snapped into the second groove 10 in the inner cavity of the first groove 6, and then the first rubber sealing block 3 and the second rubber sealing block 4 that are tightly sealed can be fixedly connected again through the Velcro 7, and at this time, it is necessary to ensure that the first hook surface 12 is bonded to the first fur surface 6, and the second hook surface 13 is bonded to the second fur surface 15;

[0034] If the device needs to be carried, the connecting card strip 17 stored in the hollow storage strip 16 can be pulled out through the carrying strip 18 in the hidden carrying structure 8, so that the paper-plastic composite packaging bag can be carried;

[0035] After use, the Velcro 7 can be torn open and the connecting strip 17 can be pushed back into the hollow storage strip 16. Then, the first rubber sealing block 3 and the second rubber sealing block 4 that are pressed and sealed together can be opened by external force. Then, the items can be taken out of the packaging bag body 1, and then the air in the packaging bag body 1 can be pressed out. Finally, the packaging bag body can be folded and stored according to the folding groove 22.

[0036] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0037] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0038] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
