[0002] A paper bag is a container made of paper, usually used for packaging items. It is composed of foldable paper sheets, often with an extendable bottom to hold more items. Paper bags have various uses, such as shopping bags, gift bags, and food packaging bags, etc. The main raw material for making paper bags is plant fiber, including cellulose, hemicellulose, and lignin components. Its production process is relatively environmentally friendly because the raw material comes from trees and other plants, only needing to go through the links of felling, papermaking, and molding, with less pollution.

[0003] The existing paper bag has poor waterproofness and is prone to damage (especially the bottom, as it is under greater stress, and is particularly prone to damage) when encountering water, which causes the loaded items to fall and affects the normal use of the paper bag. Therefore, we propose a reusable paper bag with waterproof structure. SUMMARY

[0006] Preferably, the top end of the paper bag body is fixedly connected with a sealing bag, one side of the inside of the sealing bag is fixedly installed with a fixed strip, one side surface of the fixed strip is fixedly provided with a clamping groove, and the other side of the inside of the sealing bag is fixedly connected with an elastic bone strip.

[0007] Preferably, the top of the sealing bag is fixedly connected with a first corner bag and a second corner bag respectively on both sides.

[0008] Preferably, the two sides of the paper bag body are fixedly connected with a carrying rope.

[0009] Preferably, the inner bottom surface of the paper bag body is fixedly connected with a paper waterproof base, and the outer edge of the paper waterproof base and the inner bottom inner wall of the paper bag body are in sealing connection.

[0010] Compared with the prior art, the utility model has the advantages of:

[0011] The waterproof paper base can effectively prevent water droplets generated during use of the paper bag body from penetrating into the bottom of the inside of the bag body, avoid the inside bottom of the paper bag body from being damp and damaged, further enhance the waterproof performance of the paper bag body, ensure that the bottom will not be penetrated by water, the waterproof coating can effectively block the penetration of external moisture of the paper bag body, protect the items inside the paper bag body from being affected by damp air, keep dry, the polytetrafluoroethylene microporous membrane layer increases the waterproof and moisture permeability of the inside of the paper bag body, and the waterproof membrane can effectively block the passage of water on the surface of the paper bag body, protecting the internal objects from moisture erosion.
