**6. Limitations**

Though there are many reports on the successful presentation of electrospinning as a useful platform technique for the fabrication of nanofibers from a variety of materials, several issues are yet to be explained. Electrospinning process simulation models need to be optimised by considering all the liquid properties for electrospinning and all the processing parameters for better elucidation of the phenomenology of electrified jets. If it is successful, one should be able to analyse the behaviour of the electrified jet for the deterministic fabrication of electrospun nanofibers with well-controlled size, structure, and morphology [33].

Even though there is increase in the usage of natural biopolymers in the electrospinning technique for food packaging has developed a massive growing interest in the recent years but due to lesser flexibility of these materials ultimately leads to difficulty of processing in traditional equipments, and most of them are hydrophilic materials which means that they lack necessary mechanical properties and good barrier properties to moisture and oxygen [35].
