Although there are many special types and grades of paperboard, the following list includes those most widely used in the production of the folding cartons.

Chip Boards – These boards are produced only on combination or cylinder board machines. They are low in cost and are manufactured from primarily recycled fiber.

Bending Chip – Used for the production of many types of folding cartons such as laundry boxes and other throw-away containers. It is composed of mixed fibers and by definition must be able to withstand a single fold of 180° without breakage or separation of plies. It is generally gray or tan in appearance.

Bleached Manila – Used where good bending qualities and a surface well adopted to color printing is needed. It is made with a chip board base and is lined with a white manila vat liner.

Coated Boards – These multi-layer boards (six to nine plies) are manufactured on a cylinder or combination board machine. They are usually composed of primarily recycled fiber and are used for most better grades of folding cartons.

Patent-Coated Board – Patent-coated on one or both sides with white virgin pulp or white reclaimed fibers. It is produced in many combinations including patent-coated manila, newsboard and news centered-manila back. Cost, quality, or appearance requirements dictate which combination works best for a particular order.

Clay Coated Board – Used in the production of folding cartons where brightness of color excellent printing surface and permanence of color are considered essential. It is a high grade paperboard coated with a clay finish.

Cast Coated Board – A high quality boxboard with a glossy finish obtained by pressing the surface against a highly polished surface during the drying process. Excellent where sparkling color is required

Laminated Board – This category of boxboard includes many specialty applications where foil, patterned paper, or any number of other materials are adhered to the paperboard with resin, starch, asphalt or other type of binder.

Sulfate or Kraft Board – These boards are usually manufactured on a Fourdrinier machine in a single layer and are composed entirely of virgin Kraft (sulphate) pulp. The are produced either as Bleached or unbleached board and often are clay coated to provide a white printing surface. There is also a Bogus Kraft which is an adulterated board colored brown to look like unbleached Kraft.
