Electrospinning meets food packaging: A promising pathway towards novel opportunities in food preservation

Electrospinning is a versatile, cost-effective method for manufacturing sub-micron or nano-scale polymer fibers, without requiring high temperature or pressure. This technology offers numerous advantages, including simple equipment, mild processing conditions, distinctive pore structures, and highly modifiable surface properties. Herein, we provide an overview of the various types and factors influencing electrospinning, and discuss its diverse applications in food packaging, such as intelligent packaging, antibacterial packaging, antioxidant packaging, and high-temperature/humidity-resistant packaging. We also explore the limitations of electrospinning and suggest future research directions. This review aims to deepen our understanding of electrospinning technology and provide valuable references for the development of food packaging materials.
