A Highly Hydrophobic Sustainable Starch/Gelatin-Beeswax Biodegradable Film: Easy to Industrial Scale-Up, Recyclable, and Suitable for Multiple Packaging Application Scenarios

“…Within the realm of renewable biopolymers, polysaccharides emerge as promising candidates for the replacement of petroleum-based plastics, owing to their exceptional film-forming capabilities, suitable mechanical properties, and nontoxic biodegradability. , However, the hydrophilic nature of polysaccharides material-based films limits the wide application in the field of packaging materials. , Much research has been devoted to mixing natural waxes with polysaccharides material-based films to improve their water sensitivity . Prior studies have developed pseudobilayer films by utilizing phase separation (when the continuous phase fails to stabilize the film emulsion) and buoyancy (wax upward migration) in the emulsion during the film-forming process, resulting in the formation of a surface layer enriched with wax. − Polysaccharides waxes-based pseudobilayer films exhibit enhanced efficacy in impeding water vapor transmission and hydrophobic performance compared to emulsion films, owing to a continuous hydrophobic phase on their surfaces. , To date, substantial research efforts have been dedicated to advancing hydrophobic surfaces tailored for food packaging by employing a combination of suitable micro/nanostructures and low-surface-energy materials. , Unfortunately, all of the films were prepared via a solution method, which is undesirable for industrial-scale production, primarily because of the additional high processing cost and low efficiency. Meanwhile, using polymers and waxes to construct highly hydrophobic surfaces is complex and often involves chemical reagents that increase the roughness. , Therefore, a facile, high efficiency, safe, and easily industrial scale-up method to construct highly hydrophobic polysaccharide-based films with a wax-enriched hydrophobic layer is still anticipated.…”
