Recognized as a standard of excellence for sterile medical packaging, Tyvek® 1059B offers outstanding resistance to microbial penetration, significantly reduced risk of package failure, compatibility with a broad range of sterilization methods, and a low risk of device contamination.
Even under the most rigorous conditions in highly contaminated environments, Tyvek® 1059B is highly resistant to penetration by bacterial spores and other contaminating microorganisms. Microbial barrier test data consistently prove that all styles of Tyvek® for sterile medical packaging — Tyvek® 1073B, Tyvek® 1059B and Tyvek® 2FS™ — hold out bacterial spores and test particles better than other commercially available porous medical packaging materials, including medical-grade papers. In addition, a long-term shelf life study proved conclusively that Tyvek® 1059B can maintain sterility for at least five years if package integrity is not compromised.
The tough, continuous filaments of Tyvek® 1059B help protect package integrity from both product breakthrough inside and rough handling outside. Compared to medical-grade papers, Tyvek® 1059B has superior tear strength and puncture resistance. What’s more, because it is breathable, Tyvek® 1059B minimizes the formation of condensation due to temperature extremes that can occur during transport.
Unlike medical-grade papers and films, Tyvek® 1059B is compatible with all of the most commonly used sterilization methods. So no matter which process you use for your sterile medical packaging — ethylene oxide (EO), gamma, electron-beam, steam (under controlled conditions) or newer methods (such as low-temperature oxidative sterilization) — Tyvek® 1059B will retain its protective properties, color and flexibility.
The unique structure of Tyvek® 1059B — tough, continuous filaments — creates both a tortuous path for superior microbial barrier and excellent strength properties. It also means that Tyvek® 1059B generates very few airborne particles when sterile medical packaging is opened or handled. This clean peel minimizes the risk of introducing particulates into a clean environment
