Abstract
(EN)
A method of sterilising a polymer comprises providing a polymer and exposing the polymer to UVc radiation to reduce the bioburden, for example to reduce the bioburden to a SAL value of 10-6. The method may be used to sterilise polymers, particularly biopolymers, against bacterial and fungal cells and spores. An apparatus for sterilising a polymer and a packaged polymer is also described.
(FR)
La présente invention concerne un procédé de stérilisation d'un polymère comprenant la fourniture d'un polymère et l'exposition du polymère à un rayonnement UVc pour réduire la biocontamination, par exemple pour réduire la biocontamination à une valeur de SAL de 10-6. Le procédé peut être utilisé pour stériliser des polymères, en particulier des biopolymères, contre des cellules et des spores bactériennes et fongiques. L'invention concerne également un appareil pour stériliser un polymère et un polymère emballé.
