Moisture content: Moisture content is the percentage of water in paper or board by weight. It affects stiffness, cracking at creases and warp.
In more detail
Paper absorbs and releases moisture with the air around it. Too dry and it cracks when folded; too wet and it loses stiffness and can warp corrugated board.
Why it matters
A stable moisture range keeps converting lines running and boxes square. Ask how reels are wrapped and stored.
How it is measured or specified
Measured with a moisture meter or by oven-drying a sample.

What is Cobb value?
The Cobb value is the mass of water a known area of paper absorbs in a set time, in grams per square metre. Lower means more water-resistant.
What is GSM?
GSM is the weight of one square metre of paper or board in grams. It is the basic measure of how heavy, and roughly how strong and costly, a grade is.
