Description

A generic name for a heavy Paper that is at least 0.012 inches thick. Some paperboards, such as Millboards or Mat Boards, are made from thick paper pulp castings that are milled or pressed into a hard, stiff sheet. Pasteboard is made from several laminated sheets adhered together. The term Cardboard is ambiguous and more often used for a paper product formed with a central corrugated sheet laminated with smooth exterior sheets.

Synonyms and Related Terms

Cardboard; Binder board; Millboard; Pasteboard; Corrugated board; boxboard

Applications

  • Packaging
  • Signage, printing
  • Book and magazine covers, postcards

Environmental Risks

  • Biodegradable
  • Paperboards made solely from paper fibers may be recycled. Many however, are muti-layer with coatings or adhesives than prevent recycling
  • Paper and paper boards can be made from recycle papers mixed with virgin pulp

Physical and Chemical Properties

  • Thickness = > 0.012 inches (>30 mm)
  • Density = > 0.65 g/cc
  • Grammage = > 250 g/m2 (ISO standard)

The following is the DIN standard for Paperboard - Terms and grades

First letter
(surface treatment)
Second letter
(main furnish)
Number
  • A = cast-coated
  • G = pigment coated
  • U = uncoated
  • Z = bleached virgin chemical pulp
  • C = virgin mechanical pulp
  • N = unbleached virgin chemical pulp
  • T = recycled/secondary fiber with white, cream or brown reverse
  • D = recycled/secondary fiber with grey back

All except D grades:

  1. white reverse side
  2. cream reverse side
  3. brown reverse side

D grades only:

  1. bulk ≥ 1.45 cm3/g
  2. 1.3 cm3/g < bulk < 1.45 cm3/g
  3. bulk ≤ 1.3 cm3/g

Working Properties

  • Easily cut and formed
  • Lightweight and strong
