Application of nanotechnology in food packaging system

Abstract

Hyun Jin Park

In recent years, nanotechnology is widely used in food packaging areas such as Nano barcodes for tracking and sensing, Nanoscale pigments for inks, nanomaterial for color without the use of dyes or conventional pigments, and nanomaterial electronic displays with quality paper. We diversely applied Nano-clay to biodegradable poly(lactic acid) (PLA) films, which are used instead of plastic films to reduce the growing serious environment problem, for the purpose of improvement in mechanical or barrier properties of the films. The poor moisture barrier property of a PLA film was improved by a chitosan or/and clay coating.
