[0005] To overcome the lack of sufficient air circulation space, the utility model provides a breathable corrugated paper packaging box.

[0006] The technical solution of the utility model is: a breathable corrugated paper packaging box, including corrugated paper packaging box, waterproof shell and waterproof breathable film, the outer side of the corrugated paper packaging box is wrapped with a waterproof shell, and the left and right symmetrical corrugated paper packaging boxes are installed with waterproof breathable film.

[0007] In one embodiment, it also includes a reinforcing plate, and the inner core position of the corrugated paper packaging box is provided with a reinforcing plate.

[0008] In one embodiment, it also includes a sealing plate, and the inside of the corrugated paper packaging box is connected with a sealing plate.

[0009] In one embodiment, it also includes a sponge block, and each waterproof breathable film inside is placed with a sponge block.

[0010] In one embodiment, it also includes a soft pad, and the inner side of the corrugated paper packaging box is connected with a plurality of soft pads.

[0011] In one embodiment, it also includes an anti-abrasion plate, and the outer side of each soft pad is connected with an anti-abrasion plate.

[0012] In one embodiment, the size of the reinforcing plate is designed to match the inner core of the corrugated paper packaging box.

[0013] In one embodiment, the plurality of waterproof breathable films are made of polytetrafluoroethylene.

[0014] The utility model discloses the beneficial effect has: through the waterproof and breathable membrane's setting, not only realized the free circulation of air, also effectively blocked the invasion of outside moisture, and this structure ensured the dry and stable of corrugated paper packaging box internal environment, avoided the risk that the content was damaged because of moisture accumulation simultaneously, through the design of waterproof shell, can effectively block the invasion of rain, moisture or other liquid, prevent corrugated paper material from losing strength or deformation because of water absorption, thereby guarantee the structural integrity of packaging box.
