[0006] Paper gasket, paper gasket is composite in the core of surface paper;

[0007] Hygroscopic filler, hygroscopic filler is arranged at the core paper aperture place;

[0008] Honeycomb through -hole, honeycomb through -hole is set up on core paper.

[0009] As preferred, the inner and outer sides of paper gasket are respectively composite with a layer of waterproof membrane.

[0010] As preferred, the paper gasket and waterproof membrane are filled with non -woven cloth layer.

[0011] As preferred, the height of core paper is between 2-5mm.

[0012] As preferred, the waterproof membrane is waterproof grease coating, and the thickness of waterproof membrane is not more than 0.5mm.

[0013] As preferred, the hygroscopic filler selects sponge strip.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The waterproof film can increase the waterproof property and folding resistance of the paperboard, and can increase the strength of the paperboard by cooperating with the non-woven fabric layer and the paper gasket, so that the tearing resistance of the paperboard is increased, and the moisture can be guided to the moisture absorption filler by the moisture absorption filler and the honeycomb through hole, so that the core paper is prevented from being damp and mildewed and the strength is prevented from being affected.
