In conclusion, nanotechnology will serve as an important
tool to overcome existing challenges that are associated
with packaging materials. This advancement will positively
affect the shelf-life, quality, safety, and security of foods,
which will ultimately benefit both the producers and consumers.
However, precautionary principles should be
applied and more research is needed, especially on the
migration behaviors of nanomaterials in food and their potential
impacts on health/safety, as well as the environment.
A sustainable packaging solution can be achieved only if it
is socially responsible, economically viable, and environmentally
sound.
