Tyvek® 1059B


DuPont Tyvek® 1059B for Sterile Medical Packaging

Tyvek® 1059B provides robust protection for medium-risk, sterile medical packaging applications. Lighter weight than Tyvek® 1073B, this proven performer is ideal for smaller devices and those with rounded edges. 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.

Outstanding Resistance to Microbial Penetration

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.

Significantly Reduced Risk of Package Failure

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.  

Compatibility with a Broad Range of Sterilization Methods

Unlike medical-grade papers and films, Tyvek® 1059B is compatible with all of the most commonly used sterilization methods. These include:

  • Ethylene Oxide (EO)
  • Radiation (Gamma and electron beam)
  • Steam (under controlled conditions)
  • Low temperature oxidative

So no matter which process you use for your sterile medical packaging Tyvek® 1059B will retain its protective properties, color and flexibility.

Low Risk of Device Contamination

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.
