Corrugated boxes, or “corrugated” boxes, as they are sometimes mistakenly called, are inexpensive, simple containers made from a wood and paper substance known as paperboard (though some plastic container varieties are made of corrugated plastic). They are used for the storage of a wide variety of objects in homes as well as places of business.

Corrugated boxes are sold in bulk bundles, usually of around 20 to 50, and they are shipped flattened. Many different products are made out of corrugated cardboard, including pizza boxes, appliance boxes, jewelry boxes, boxes for moving and shipping, storage boxes, cake boxes, retail boxes and many other examples. The most common corrugated boxes are medium-sized, square or rectangular boxes, but some custom corrugated boxes are small enough to hold a pair of earrings, while others are large enough to serve as packaging for a big screen television or a kitchen appliance. Most corrugated cartons and boxes are considered folding boxes, meaning they are held in place by folding flaps together. Not all corrugated boxes are made of wood or paper; some are fabricated from molded plastic. These are used when a stronger material is needed, when the box contains liquids or chemicals or when it must be able to lock.
Corrugated boxes differ in shape, size, thickness, durability, color, finish and method of holding together. To form the box shape, the flat pieces of cardboard are held together by tape, folding flaps, heavy duty staples or an adhesive. Sometimes the exterior is bleached or mottled, which takes away the dark brown pigment and replaces it with an attractive white finish. Corrugated boxes that contain commercial products like cereal, soap and toothpaste have a laminated, colorful and glossy exterior that is often colorful and can be adorned with a logo, brand name and informational text. The corrugated layer in cardboard boxes is manufactured with high-precision machinery that can produce 500 feet of paper board per minute. It is done in a humid area to soften the paperboard. With pressure, it is sandwiched in between two flat molds with a rippled pattern. Today, these boxes are very popular because they are quick and inexpensive to manufacture, cheap to ship because they are so lightweight and can be used over and over again. When in storage, most can be folded down flat.
