Issue 34: Nanomaterials in Packaging; Food Packaging; Anti-counterfeiting; Chemical, Biological and Explosive Threat Detection

Nanomaterials have already been commercialized at various stages of the packaging supply chain from food storage to traceability and tracking. Their enhanced properties, such as UV protection, barrier to moisture, gases and volatile components, mechanical strength, significantly improve packaging materials. Nanomaterials also play a key role in the development active and smart packaging technology. The use of nancomposites with biopolymers is also on the rise as the use of biodegradable packaging increases. Concerns about costs in comparison to traditional packaging and consumer acceptance have thus far hindered widespread up- take. We investigate this market and companies developing products.

Counterfeiting is a huge global problem, with 2-5% of all international trade involving counterfeit goods. Companies spend more than $14 billion each year to battle the problem and are investing in new anti-counterfeiting and brand-protection technologies. Nanomaterial enabled products are at the forefront of the fight in markets ranging from luxury goods to pharmaceuticals.

Defence against biological and chemical agents and environmental security are viewed as key priority areas for global security. Chemical and biological threats pose a significant concern not only to military personnel but also to individuals and groups. Nanomaterials and nanotechnology can play a vital role in the detection and decontamination of chemical and biological threat agents. Nanosensors are allowing for improved detection, decontamination and protection against chemical, bio-agents and explosive threats.
