Nanotechnology is the technology of the very small, with nanomaterials having at least one dimension in the range 1 to 100 nm where 1 nm is 1 × 10–9 m. Nanotechnology is making a large difference to products across industry, and nano-enabled products are now being used extensively in packaging with the Fast-Moving Consumer Goods sector driving developments of new products. These include nano-enabled packaging to deliver enhanced shelf life of food and pharma products and low-cost security tags. The list will continue to grow as companies realise the added value they can deliver with nano-enabled packaging.
