Hydrophobization of Cellulose-Based Fibers for Packaging Applications with Alkyl Ketene Dimers (AKD) and Food-Grade Waxes via Supercritical Impregnation with Carbon Dioxide – Experimental and Thermodynamic Modeling Approaches
This modified material has applications in food packaging, where frequently water-repellant surfaces are required. This method is preferable to traditional coating methods because it sizes across the entire thickness of the substrate rather than just the surface and can be used for non-planar surfaces; uses significantly less material than traditional methods and will be an excellent technique for multilayered and intelligent coating.
