Machined grey paperboard is glazed on one side, produced from up to 100% recovered pulp (post-consumer) and used primarily as packaging material. It can, however, also be used in bookbinding, handicrafts or model making.

Because grey paperboard is made from recovered paper and is not bleached it can be that the grey tones will vary slightly in the different thicknesses.
Even the thicknesses among a given specification can vary as well.
