Innovative Fabrication of Emulsion‐Derived Electrospun Nanofibers in Food Packaging

Food packaging plays a vital role in maintaining food safety, quality, and shelf life by protecting products from moisture, oxygen, light, and microbial contamination. However, conventional packaging materials face limitations such as chemical migration, poor biodegradability, and lack of active functionality. In recent years, nanotechnology, especially electrospinning, has proved to be a promising strategy for developing advanced food packaging materials. Emulsion‐derived electrospun nanofibers enable the incorporation of bioactive compounds such as antimicrobials, antioxidants, and oxygen scavengers within biodegradable polymer matrices. Biogenic and bio‐derived polymers including chitosan, cellulose, keratin, polylactic acid (PLA), polycaprolactone (PCL), and poly3‐hydroxy butyrate) (PHB) have demonstrated significant potential in improving mechanical strength, barrier properties, and controlled release behavior. This review discusses fabrication strategies, material selection, and functional performance of electrospun nanofibers in food packaging applications. Furthermore, current challenges related to scalability, regulatory compliance, and cost‐effectiveness are addressed, highlighting future directions for sustainable and intelligent packaging systems.
