Corrugating Industry - Controlling Warp
Moisture, Temperature, or Both for Control?
Cross Direction (CD) warp is when the top and bottom liner board moistures are not matched and it is the largest contributor to board quality. If the top and bottom liner board moisture levels are unequal after bonding, the variance in shrink rate will cause warp. Machine Direction (MD) warp can be caused by moisture variations between the top and bottom liners and tension control.
Warp Control and Flatness can most reliably be achieved with the incorporation of moisture transmitters into the control scheme.
