Investigations At The Product, Macromolecular, And Molecular Level Of The Physical And Chemical Properties Of A 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 gamma-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 gamma-irradiation. Furthermore, our investigations are focuses on properties/events occurring at product, macromolecular, and molecular levels.
