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

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

- Grammage = > 250 g/m2 (ISO standard)
"Paperboard - Terms and grades" (Publication date : 2005-09) defines different grades of paperboard based on the surface treatment (first letter), the main furnish (second letter) and the colour (non-D grade) or bulk (D grade only) (numbering).
| First letter (surface treatment) |
Second letter (main furnish) |
Number |
|---|---|---|

Example: GC1 would be a "pigment coated", "virgin mechanical pulp" board with a "white reverse side". Often the used paperboard type would be FBB, which was coated on both sides.
Working Properties
- Lightweight, Easily cut and formed
- Strong
