How can paper, paperboard or corrugated cardboard be distinguished?

Proper paper has a grammage of up to 150 g/m2, while cardboard features a grammage in excess of 600 g/m2, and as high as 1100 g/m2. Paperboard, on the other hand, is a paper-based material with a grammage that lies between paper and cardboard, identified by a grammage in the 250 to 450 g/m2 range.

If we look at the above figures, we can see that there are two apparently undefined ranges, namely between 150 and 250 g/m2, and between 450 and 600 g/m2: within these ranges, the line between paper and paperboard (in the case of the former range) and between paperboard and cardboard (in the case of the latter) is a little blurred.
