Magnetic Folding Gift Box 2mm 2.5mm Rigid Board Gift Packaging

Material Structure and Application

Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 points) than paper and has certain superior attributes such as foldability and rigidity. According to ISO standards, paperboard is a paper with a grammage above 250 g/m², but there are exceptions. Paperboard can be single- or multi-ply.

Paperboard can be easily cut and formed, is lightweight, and because it is strong, is used in packaging. Another end-use is high quality graphic printing, such as book and magazine covers or postcards.

Sometimes it is referred to as cardboard, which is a generic, lay term used to refer to any heavy paper pulp–based board, however this usage is deprecated in the paper, printing and packaging industries as it does not adequately describe each product type.

Terminology and classifications of paperboard are not always uniform. Differences occur depending on specific industry, locale, and personal choice. In general, the following are often used:

Boxboard or cartonboard: paperboard for folding cartons and rigid set-up boxes.

Folding boxboard (FBB): a bending grade capable of being scored and bending without fracture.

Kraft board: a strong virgin fiber board often used for beverage carriers. Often clay-coated for printing.

Solid bleached sulphate (SBS): clean white board used for foods etc. Sulphate refers to the kraft process.

Solid unbleached board (SUB): board made from unbleached chemical pulp.

Containerboard: a type of paperboard manufactured for the production of corrugated fiberboard.

Corrugated medium: the inner fluted portion of corrugated fiberboard.

Linerboard: a strong stiff board for one or both sides of corrugated boxes. It is the flat covering over the corrugating medium.
