The use of nanofillers opens an opportunity for developing innovative and high-performance packaging materials. Accurately, nanotechnology is having an impact on several aspects of food science, from how food is grown to how it is packaged.
Companies are developing nanomaterials that will make a difference not only in the taste of food, but also in food safety, and the health benefits that food delivers. Applications include nano‐filler reinforced packaging (e.g. enhanced barrier properties), active packaging (e.g. antimicrobial), intelligent packaging (e.g. freshness indicators), and biodegradable packaging. Clay nanocomposites are being used to provide an impermeable barrier to gasses such as oxygen or carbon dioxide in lightweight bottles, cartons and packaging films. Storage bins are being produced with silver nanoparticles embedded in the plastic. The silver nanoparticles kill bacteria from any material that was previously stored in the bins, minimizing health risks from harmful bacteria.
