Nano in food packaging – is this already on the market and is it safe?

In food packaging many different materials are used and for nanomaterials many application possibilities exist, thus, there is no general answer. There are surely products on the market, which contain nanomaterials or nanosized coatings. Within the EU materials intended to come into contact with food must be sufficiently inert to preclude any adverse effect for human health (Regulation (EC) No 1935/2004) and this is totally independent of the particle size or the type of material.
