INTROUDUCTION TO FBB AND SBB

Folding boxboard also referred to as FBB, GC, UC.

FBB construction:

1 - Coating

2 - Bleached chemical pulp

3 - Mechanical pulp

4 - Unbleached/Bleached chemical pulp

FBB is a paperboard grade which is made up of multiple layers of chemical and mechanical pulp.[1]. This grade is made up of mechanical pulp in between two layers of chemical pulp. The top layer is of bleached chemical pulp with an optional pigment coating.[2] This is a low density material with high stiffness and has a slightly yellow colour, mainly on the inside. The major enduses of folding boxboard are health and beauty products, frozen, chilled and other foods, confectionaries, pharmaceuticals, graphical uses[3] and cigarettes [4].

Solid Bleached Board also known as, SBB or GZ is a virgin fibre grade of paperboard.

This grade is made purely from bleached chemical pulp and usually has a mineral or synthetic pigment[1] coated top surface in one or more layers as well as a coated reverse side. It is a medium density board with good printing properties for graphical and packaging end uses and is perfectly white both inside and out. It can easily be cut, creased, hot foil stamped and embossed. Its other properties, such as being hygienic and pure with no smell and taste, make it usable for packaging aroma and flavour sensitive products such as chocolate, cigarettes and cosmetics.[2]

Paperboard

There are two basic types of paperboard used to produce folding cartons: Virgin Fiber and Recycled Fiber or Combination.

Virgin Fiber Paperboard Grades

SBS Paperboard (Solid Bleached Sulfate)

Bleached paperboard or solid bleached sulfate (SBS) is a premium paperboard grade that is produced from a furnish containing at least 80% virgin-bleached wood pulp. Most bleached paperboard is coated with a thin layer of kaolin clay to improve its printing surface and may be also coated with polyethylene (PE) resin for wet strength food packaging.

Coated Unbleached Kraft Paperboard (CUK)

Clay natural kraft (CNK®) made by MeadWestvaco Corporation or solid unbleached sulfate (SUS®) made by Graphic Packaging International, Inc. is a superior strength paperboard grade that is produced from a furnish containing at least 80% virgin unbleached, natural wood pulp. Most unbleached or natural kraft paperboard is coated with a thin layer of kaolin clay to improve its printing surface and may be also coated with polyethylene (PE) resin for wet strength food packaging.

Recycled Fiber or Combination Paperboard Grades

Uncoated Paperboard

Uncoated recycled paperboard, a multiply material, is produced from 100% recovered paper -collected from paper manufacturing and converting plants and post consumer sources- and represents the single largest market for recovered paper in the United States. Some uncoated paperboard is produced with a top ply of white recovered fiber or vat dyed for color.

Coated Paperboard

Coated recycled paperboard, a multiply material, is produced from 100% recovered paperboard just as uncoated paperboard; however, typically coated with a thin layer of kaolin clay over a top ply of white recovered fiber to improve its printing surface.
