Common Issues with Corrugated Board Produced on Corrugator Line
1. Board Warping Problem Description: After leaving the corrugated cardboard production line , the board is not flat but curves upward, downward, or to one side. Cause Analysis: Uneven moisture content: This is the core cause. Different parts of the cardboard (face paper, liner paper, core paper) have inconsistent moisture levels, leading to varying drying shrinkage rates. 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,...
