ABSTRACT
The increased interest in the development of biodegradable and renewable materials for food packaging applications has increased research on new strategies to improve their barrier performance. This chapter describes the potential of the electrohydrodynamic processing technique (EHDA) for the development of nanostructured layers of interest in food packaging. The most common process of the EHDA is the so-called electrospinning technique. Electrospinning is a simple, versatile, and efficient method to produce high-performance polymeric fibers with diameters ranging from the micro to the nanoscale. One of the most innovative applications of electrospinning is the fabrication of nanostructured multilayers with tailor-made physical properties such as barrier properties. For this application, this technique is very promising, since it allows to act as a functional layer and also as a tie layer, promoting adhesion between the constituting layers. This chapter compiles innovative strategies that make use of multilayer systems to achieve optimized barrier performance.
