Upward Warping: Typically caused by excessively high moisture content in the face paper or overly dry liner paper. The face paper has a higher shrinkage rate than the liner paper. Downward Warping: Opposite of upward warping, caused by excessively high moisture content in the liner paper or overly dry face paper. The liner paper has a higher shrinkage rate than the face paper. S-curve warping: Lateral warping usually caused by uneven cross-directional temperature on the production line or inherent paper defects. Inappropriate base paper combination: Significant disparities in physical properties (basis weight,...
