Embodiment Construction

[0009] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0010] like figure 1 As shown, the waterproof corrugated box includes a box body, and the box body is made of corrugated paper 1. The corrugated paper includes inner and outer box board layers 2, 3 and a corrugated layer 4. The double sides of the corrugated layer 4 are bonded with waterproof membranes 5, and the corrugated paper Layer 4 is arranged between the inner and outer box ply layers 2 and 3, and bonded to the inner and outer box ply layers 2 and 3.

[0011] Both sides of the corrugated layer 4 of the corrugated paper 1 of the waterproof corrugated box are provided with waterproof membranes 5, and the liquid entering from the outside will not enter the box to ensure that the items in the box are dry. The liquid in the box will not flow out and will not leak to the outside of the box, preventing the liquid leaking from the box from...
