Abstract: Recently, food packages produced with nanoparticles, “nano-food packaging,” have become more available in
the current market. However, although the use of nanomaterials is increasing in food packaging applications, concern over
toxicity affects consumer perceptions and acceptance. Quite a number of commercialized forms of nano-food packaging
are coated or composited product with inorganic materials, for example, nanosilver and nanoclay as representative
examples. Several studies have shown the possibility of nanomaterial migration from packaging or containers to foodstuff.
The debate is still ongoing among researchers about the extent of migration and whether it is negligible and safe.
Government agencies and stakeholders must hurry to determine use limitations and release conclusive legislation and
regulations as soon as possible since nano-food packaging may have great impacts on human health. This paper aims
to review the availability of nano-food packaging in the current market, report case studies on nanomaterial migration,
and present the current status of safety regulations and management of nano-food packaging in leading countries across
regions. This review should enable governments and researchers to develop further nanomaterial risk assessment studies.
