Corrugated Packaging Box
Corrugated boxes are light yet sturdy boxes that are made by folding corrugated paperboards. The basic structure of corrugated boxes involves boards made from sandwiching fluted or arched paper between two layers of lining boards made from heavy paper. This gives corrugated boxes a higher bending rigidity and resistance to crushing than most other packaging boxes. Lighter and low-cost corrugated boxes are used in retail packaging or in packaging food. Pizza boxes, for instance, are made from single-walled corrugated boards.
