Cardboard is a generic term for a heavy-duty paper of various strengths, ranging from a simple arrangement of a single thick sheet of paper to complex configurations featuring multiple corrugated and uncorrugated layers.
Despite widespread use in general English, the term is deprecated in business and industry. Material producers, container manufacturers, packaging engineers, and standards organizations, try to use more specific terminology. There is still no complete and uniform usage. Often the term "cardboard" is avoided because it does not define any particular material.
The term has been used since at least as early as 1683 when, with a publication of that year stating that "The scabbards mentioned in printers' grammars of the last century were of cardboard or millboard". The Kellogg brothers first used paperboard cartons to hold their flaked corn cereal, and later, when they began marketing it to the general public, a heat-sealed bag of Wax paper was wrapped around the outside of the box and printed with their brand name. This marked the origin of the cereal box, though in modern times, the sealed bag is plastic and is kept inside the box rather than outside. Another early American packaging industry pioneer was the Kieckhefer Container Company, run by John W. Kieckhefer, which excelled in the use of fibre shipping containers, which especially included the paper milk carton.
Various types of cards are available, which may be called "cardboard". Included are: thick paper (of various types) or pasteboard used for business cards, aperture cards, postcards, playing cards, catalog covers, binder's board for bookbinding, scrapbooking, and other uses which require higher durability than regular paper.
Paperboard is a paper-based material, usually less than about ten mils (0.010 inches (0.25 mm)) in thickness. It is often used for folding cartons, set-up boxes, carded packaging, etc. Configurations of paperboard include:
Modernly, materials falling under these names may be made without using any actual paper.
Corrugated fiberboard is a combination of paperboards, usually two flat liners and one inner fluted corrugated medium. It is often used for making corrugated boxes for shipping or storing products.
Most types of "cardboard" are recyclable. Boards that are laminates, wax coated, or treated for wet-strength are often more difficult to recycle. Clean cardboard (i.e. cardboard that has not been subject to chemical coatings) "is usually worth recovering, although often the difference between the value it realizes and the cost of recovery is marginal". Cardboard can be recycled industrially, or for home uses. For example, cardboard may be composted or shredded for animal bedding.
