[0002] Corrugated cardboard is a multi-layer bonded cardboard. It is composed of at least one layer of corrugated sandwich board core and a multi-layer cardboard structure made by gluing the board surface cardboard together. Due to its structural characteristics, corrugated cardboard has high mechanical strength and can withstand collisions and falls during transportation. It is widely used as a carton packaging material.
