Hygral Stress Dynamics and Edge Waving Mechanics in Recycled Paperboard Skids
Hygral edge waving in recycled paperboard skids results from perimeter moisture absorption driving compressive buckling against a dry, rigid core.

Inline acoustic time-of-flight profiling maps internal board ply delamination at line speed, preventing cartoner jams without marking finished carton surfaces.

Ultrasonic attenuation decay rates directly quantify paperboard crease delamination depth, enabling real-time inline verification of folding stiffness.
