MATto, Politecnico di Torino’s material library, proposed within Terra Madre - Salone del Gusto 2020, a support to companies and designers interested in new material and technological challenges of food packaging: solutions, today, are linked to disciplines from chemistry to technological culture, from semiotics to perception, to design. MATto investigated these issues, with attention to sustainability, aesthetics, and inclusion, developing a new accessible learning model for extended audience.
