[0002] A corrugated board is a multi-layer bonded body, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of the corrugated board depends on three factors: the characteristics of the core paper and cardboard, and the structure of the carton itself.

[0003] Corrugated board refers to a plate-shaped object formed by bonding the face paper, the inner paper, and the corrugated paper in a wave shape formed by processing through a corrugating roll. Under high temperature and high pressure, through the biting pressure between the upper and lower corrugating rolls in the single-sided unit, the corrugated base paper is bent and shaped during ironing to form corrugations. Subsequently, glue is applied between the inner paper and the corrugations, and the inner paper and the corrugations are bonded to form two layers of corrugated paper. Then, the face paper is adhered through a laminating machine, and finally, the two layers of corrugated paper with the face paper adhered are pressed together through a hot plate at a suitable pressure to form a corrugated board.

[0004] During the processing of corrugated board, the natural cooling time of the just-dried corrugated board is relatively long, which will reduce the processing efficiency of the corrugated board. At the same time, the high-temperature corrugated board will absorb the moisture in the surrounding air during the natural cooling process, which will affect the drying effect after drying.
