Exploratory study on how sub-ply fiber orientation affects t
ABSTRACT: The transition to 100% biobased packaging presents considerable challenges, particularly in the development of a petroleum-free barrier. Generally, biobased barriers exhibit lower flexibility compared to traditional barriers, thereby increasing the risk of cracking during the converting process. The present study examines the possibility of optimizing the substrate to reduce cracking in brittle barriers. Five three-ply composites were fabricated using commercial paperboard to enable a composite with different fiber orientation in the individual plies. The different orientations achieved varying mechanical properties, including strain-atbreak and folding resistance, with a ranking that is comparable to a standard multi-ply paperboard. The composites were subjected to creasing at five distinct depths to assess the area percent of barrier cracks across the crease bead. Micro-cracks appeared on the surface before larger coating cracks were registered. As expected, the area percent of barrier cracks increased significantly with greater creasing depths. The orientation of the bulky middle ply showed little difference in the cracking propensity. However, by replacing the stiffer bottom ply with a ply of lower stiffness, the cracking propensity was significantly reduced without a substantial loss in mechanical properties. Hence, these findings indicate that it is possible to reduce the cracks in the barrier by modifying the fiber orientation in the different plies.
