This study summarizes different types of electrospinning techniques used for the preparation of PLA-based nanofibers, and describes their enhanced properties. The application of introducing different components into nanofibers to develop active and intelligent packaging materials is also highlighted. Overall, PLA-based nanocomposites have promising prospects for food packaging applications.
ABSTRACT: Poly(lactic acid), also abbreviated as PLA, is a promising biopolymer for food packaging owing to its environmentalfriendly characteristic and desirable physical properties. Electrospinning technology makes the production of PLA-based nanomaterials available with expected structures and enhanced barrier, mechanical, and thermal properties; especially, the facile process produces a high encapsulation efficiency and controlled release of bioactive agents for the purpose of extending the shelf life and promoting the quality of foodstuffs. In this study, different types of electrospinning techniques used for the preparation of PLAbased nanofibers are summarized, and the enhanced properties of which are also described. Moreover, its application in active and intelligent packaging materials by introducing different components into nanofibers is highlighted. In all, the review establishes the promising prospects of PLA-based nanocomposites for food packaging application.
