Abstract:
Packaging materials for food containers need to fulfil extremely tight standards towards the fresh-like quality maintenance of packed products. Even though polymers are normally preferred for the production of packaging systems, their permeability to gases, water vapour and odours remains a concern. In this sense, new approaches using nanoscale effects are under development to design, create or model gas-barrier nanocoatings with significantly optimized properties. It is generally agreed that the final barrier performances of the deposited inorganic materials are strongly ...
