Sterilisation Wrap or Rigid Sterilisation Containers?

Wrap_Containers

New study1 shows that after terminal sterilisation 100% of the packages wrapped in HALYARD* sterilisation wrap are free of bacterial contamination.

A recent study showed – after terminal sterilisation – that 100%1 of the sterilised packaged wrapped in HALYARD* sterilisation wrap remained sterile whereas 87%1 of rigid sterilisation containers did not maintain sterility through transport and handling.

Surprisingly also 72%1 of new sterilisation containers showed contamination.

You may want to learn more about the bacterial barrier performance of HALYARD* Sterilisation wrap and/or the performance of rigid containers: this web page provides you with summaries of clinical, peer reviewed publications.

In this study, various types of packaging material, including containers are challenged with latex particles. This study is performed by TNO who developed the so called final pack test. The study confirms the efficiency of the Halyard One-Step packaging technique.

Using the final pack test after an 18 minutes sterilisation cycle the study demonstrates that HALYARD* sterilisation wrap is not affected by the prion cycle. The study also includes results 3 months post sterilisation. This study was funded by Kimberly-Clark, predecessor corporation to Halyard Health, Inc

Research for the sterility maintenance study was funded by Halyard Health, Inc., a manufacturer of sterilisation wrap.

161 wrapped trays were tested.

111 rigid containers were tested. Out of 111 rigid containers tested, 14 (12.6%) had no bacterial ingress, 25 (22.5%) had ingress of 1-9 CFU, 52 (46.8%) had ingress of 10-99 CFU, and 20 (18.0%) had ingress >100 CFU.

72% of unused containers showed bacterial ingress.
