Effect of the Sterilization Process on the Properties of Adhesive Foils Dedicated to Criminal Trace Evidence

This study aimed to evaluate the impact of sterilization of low-adhesive films with ethylene oxide (EO) or accelerated electrons (radiation sterilization) on their performance in the context of their use to protect forensic traces. It was hypothesized that the implementation of the sterilization process made it possible to obtain functional tools for securing traces. The analysis showed that changes in surface density, density, tensile strength, and adhesion strength do not significantly affect the functional performance of the tapes. Additionally, no alterations in chemical resistance were observed following either sterilization method. The results confirm that both sterilization techniques are suitable for obtaining sterile tapes for forensic applications.
