This project aims to develop advanced packaging solutions for both rigid and flexible formats, through the implementation of innovative materials and technologies capable of delivering high barrier properties and antimicrobial functionality.

The activities include the functionalization of polyolefins by incorporating bio-based additives, such as nanocellulose, to create mono-material structures with intrinsic barrier properties—overcoming the recyclability limitations of current multilayer films. In parallel, active coatings based on natural extracts with antimicrobial activity will be developed, designed to modulate the release of active substances depending on environmental conditions and the characteristics of the food product.

These solutions will be integrated through innovative deposition technologies, including atmospheric plasma treatments and functional coatings applicable also to metallic substrates, as a replacement for current hexavalent chromium-based passivation. In this context, the technological suitability of an innovative coating called CFPA (Chrome Free Passivation Alternative) in contact with food products will be evaluated.
