Investigations at the Product, Macromolecular, and Molecular Level of the Physical and Chemical Properties of gamma -Irradiated Multilayer EVA/EVOH/EVA Film: Comprehensive Analysis and Mechanistic Insights.

Chemically and biologically safe storage of solutions for medical uses is a daily concern for industry since decades and it appeared even more dramatic during the last two years of pandemia. Biological safety is readily reached by sterilization using -irradiation process. However, such a type of irradiation induces the degradation and the release of chemicals able to spoil the biological solutions. Surprisingly, there are no investigations on multi-layer films combining multi-technique and multi-method approaches to unveil the events occurring during -irradiation. Furthermore, our investigations are focuses on properties/events occurring at product, macromolecular, and molecular levels.
