Increasing Moisture Contentan overview ScienceDirect

Increasing moisture content also leads to paper swelling whilst drying makes it shrink. As an example between 0 and 90 RH dimensions can change by 0.8 in the MD and 1.6 in the CD. Poor humidity control can cause distortion in a blank which can compromise subsequent folding into the final container.
