Corrugated boxes: (corrugated board, corrugated fiberboard or combined board) are what you would commonly refer to as brown cardboard boxes or shipper boxes.
A wavy or fluted layer sandwiched between two outer flat layers. The fluted layer is where the strength of this paper product lines.
Folding boxes are the most commonly used for nearly every type of product sold, from cereal to medicines to chocolates or anything in a box. In the case of heavier products or high-end ones, you will typically find a rigid box. You are less likely to see a product sold in a corrugated box. Instead of being used for individual product packaging, these boxes are usually used to ship multiple products at once. Even so, you may also spot primary retail packaging made of corrugated boxes, particularly with extremely heavy or fragile products. Because of its strength, corrugated fiberboard is common for stand-up displays as well.
