Creasing Die Geometry Adjustments for Barrier Film Integrity Preservation

Modifying creasing matrix channel width and male rule tip radius prevents polymer film elongation cracking and maintains gas barrier integrity across folded scores.

A cracked material block with a metallic insert, a processing tool, blue powder, and sample rings sit on an industrial workbench.

Repulpability Certification Aqueous Dispersion Non-Fluorinated Barrier

Pinhole Permeability Testing and Score Crease Barrier Integrity in Non-Fluorinated Bakery Wraps

Non-fluorinated bakery wraps maintain grease barrier integrity when dispersion elasticity exceeds score tensile strain to stop pinhole leakage.
