Development of innovative food packaging materials

This branch of our research aims to design and develop new packaging structures inspired to the packaging optimization concept, i.e. reducing the upstream amount of plastics while keeping (or even improving) the overall performance of the final package for the main shelf life extension goal. While several solutions are continuously conceived and tested, coating technology is by far the leading strategy adopted within our team. High performance coatings have been developed by different approaches, such as soft chemistry (e.g., sol-gel technology), hard chemistry (functionalization, grafting, etc.), and nanotechnology routes (bottom-up and top-down schemes).

Our main objectives:

  • Gas and vapor barriers
  • Optical properties
  • Anti-fog properties
  • Mechanical properties
  • Anti-scratch
  • Printability
  • Sealing
  • Friction
  • Adhesion

Keywords:

Polylactic acid (PLA), termoplastich starch, polysaccharides, biopolymers, nanocomposites, inorganic fillers, inorganic nanoparticles, modified nanoparticles, coatings, macromolecular antioxidants, encapsulation, nanostructures, oxygen barrier, surface properties
