Multi-layer composite environment-friendly moisture-proof corrugated board

The utility model relates to the technical field of corrugated boards, in particular to a multi-layer composite environment-friendly moisture-proof corrugated board. Comprising a paperboard body, the paperboard body comprises anti-bending waterproof layers, reinforcing layers and a board layer, the reinforcing layers are arranged at the upper end and the lower end of the board layer, the anti-bending waterproof layers are arranged on the sides, away from the board layer, of the two reinforcing layers, the board layer comprises an inner paperboard and a corrugated paper core, and the corrugated paper core is fixed to the center of the interior of the inner paperboard. Due to the polyglycolic acid material characteristic of the hydrophobic covering film, the paper board is made of the aliphatic polyester high polymer material with high degradation speed, the paper board is green, environment-friendly and pollution-free, the waterproofness of the paper board is effectively improved, and the board body is prevent
