Poly(lactic acid), also abbreviated
as PLA, is a promising biopolymer
for food packaging owing to its environmental-friendly 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 PLA-based 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
