Composite corrugated board

The composite corrugated board is provided with two panels along the outermost side in the thickness direction, and at least two layers of corrugated core panels are integrally bonded between the two panels, wherein the corrugated directions of two adjacent corrugated core panels are staggered.

The composite corrugated board of the utility model is not only light in weight, less material used, and low in cost, but also the interlaced corrugated core board greatly improves the stress structure of the board, increases the strength of the board, and the load-bearing and compressive performance are also greatly improved. Improved, so that the board of the utility model can be used more widely.

As shown in Figure 1, this structure is a cross-composite product of double-sided corrugated board and single-sided corrugated board.
