Recognized as a standard of excellence for form-fill-seal and less demanding packaging applications, Tyvek® 2FS™, the lightest form of medical and pharmaceutical packaging styles of Tyvek®, offers outstanding resistance to microbial penetration, significantly reduced risk of package failure, compatibility with a broad range of sterilization methods, a low risk of device contamination and the ability to withstand transportation challenges.
Even under the most rigorous conditions in highly contaminated environments, Tyvek® 2FS™ is highly resistant to 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, an accelerated aging study proved conclusively that Tyvek® 2FS™ shows no change in microbial barrier properties after withstanding extreme conditions.
The tough, continuous filaments of Tyvek® 2FS™ help protect package integrity from both product breakthrough inside and rough handling outside. Compared to medical-grade papers, Tyvek® 2FS™ has superior tear strength and puncture resistance.
Unlike medical-grade papers and films, Tyvek® 2FS™ is compatible with all of the most commonly used sterilization methods. So no matter which process you use for sterilizing your form-fill-seal package — ethylene oxide (EO), gamma, electron-beam, steam (under controlled conditions) or newer methods (such as low-temperature oxidative sterilization) — Tyvek® 2FS™ will retain its protective properties, color and flexibility.
The unique structure of Tyvek® 2FS™ — tough, continuous filaments — creates a tortuous path that results in microbial barrier and strength properties superior to those of medical-grade papers. It also means that Tyvek® 2FS™ generates very few airborne particles when sterile form-fill-seal packaging is opened or handled. This clean peel minimizes the risk of introducing particulates into a clean environment.
Another distinct advantage that Tyvek® 2FS™ has over medical-grade papers and films is its ability to withstand the significant temperature and pressure changes commonly encountered during shipping. Because it is breathable, Tyvek® 2FS™ minimizes the formation of condensation due to temperature extremes that can occur during transportation. This breathability also allows medical packages made with Tyvek® 2FS™ to equilibrate rapidly from the pressure changes that occur not only during shipping but also in storage environments.
