A corrugated box consists of two or more sheet plates and is made of corrugated board. In the United States, nearly all of the panels used to make cardboard are made of kraft, a type of paperboard made primarily from untreated softwood fibers. Most of the corrugated media is obtained by a semi-chemical pulping process, which also uses mostly untreated fiber, but in this case, it is predominantly hardwood. 

Corrugated mailer boxes transport 90 to 95 percent of American-made goods to their customers. This requires the production of more than 25 billion of these tough boxes per year. In fact, corrugated boxes are the largest segment in the packaging industry.

Why is it so widely used? On average, corrugated cardboard boxes cost less than one percent of the value of the goods they transport. This makes it the most economical container ever produced with multiple protective functions. They minimize distribution costs while protecting their content as it moves from the production site to the point of consumption. Liquids, solids, granular materials – hard or soft – strong or sensitive – can easily be protected from damage in transit. Inner packing pieces can be placed in the box before filling or placed around the product after insertion.

Each corrugated cardboard box has been developed specifically for the product it contains. Size, weight, shape, fragility, orientation in packaging, filling requirements, pallet model, storage requirements, and the shipping method are all taken into account in the design. The box is then made to the right specifications. Shipping damaged corrugated cardboard boxes can be arranged quickly and easily if needed.
