Sterilization Methods
Ionizing Radiation
-
-
-
Not Acceptable
- Radiation Sterilization results in chain scission in HDPE, and cause changes in mechanical properties in the packing material
-It caused HDPE to turn yellow during sterilization
Autoclave
-
-
Autoclave sterilization works by using heat to kill microorganisms such as bacteria and spores. The heat is delivered by pressurized steam. Pressurization allows the steam to reach the high temperatures that are required for sterilization.
EtO Sterilization
-
Advantages
-Compatible with a wild range of material, thus polymers are unaffected by EtO treatment.
-Allows EtO gas and water vapour to enter the package and sterilize the contents.
Disadvantages
-Toxic and flammable
-Residual of EtO on the polymer hence it needs to be treated.
-It is not eco-friendly
