Recyclable food packaging: quality control for nanocoatings

Across the EU, more than 300 billion items of packaging are not recycled every year because they consist of a mixture of different materials. Monomaterial packaging on the other hand is easy to recycle. However, it needs to be coated with ultra-thin barrier layers to protect delicate products just as well as compound materials do. Fraunhofer IPM is developing an optical measurement system enabling the inline quality control of these barrier layers.
