Entkeimen von Packstoffen beim aseptischen Abpacken. 7. Mitteilung: Untersuchungen zur Sterilisation von Packstoffoberflächen durch eine Kombination von Wasserstoffperoxid-Bedüsung und UV-C-Bestrahlung

In this study we investigated if sterilization of packaging materials during aseptic packaging will be facilitated by a combined treatment of hydrogen peroxide and UV-C-irradiation compared with UV-treatment alone. We could demonstrate an increased microbial reduction by the combined treatment by a factor of 5 at best, but the increase was not as high as originally expected. This could be explained by the fact that hydrogen peroxide sprayed upon hydrophobic plastic films only cover a part of total surface (about 40%) with small droplets
