Expanded information corrugated board first started at the end of 18. /kloc-in the 20th century, it was found that corrugated board was not only light in weight and firm in performance, but also cheaper than ordinary materials, with simple manufacturing process and wider application. Moreover, corrugated board is not only a recyclable environmental protection material, but also composed of wood fibers, which can be decomposed by natural action and can be reused without affecting its performance.

Therefore, it is favored by people.
