Tyvek® 1073B


Durable Medical Device & Pharmaceutical Packaging for Demanding Applications

Made of high-density polyethylene (HDPE), Tyvek® offers exceptional protection against damage for sharp or heavy products, outperforming more fragile alternative materials, such as medical-grade paper. Its strength helps Tyvek® 1073B protect and maintain the sterility of high-risk medical products, from artificial hips to heart valves.

High-Strength Protection for High-Risk Products

Tyvek® 1073B provides the highest level of protection, making it the ideal choice for medical device and pharmaceutical packaging that requires high strength and superior microbial barrier. DuPont Tyvek® 1073B has the highest strength of all Tyvek® styles for medical device and pharmaceutical packaging.

In addition, Tyvek® 1073B is compatible with a broad range of manufacturing and sterilization processes and is a superior microbial barrier, to help preserve sterility during both shipping and storage.

Outstanding Resistance to Microbial Penetration

Even under the most rigorous conditions in highly contaminated environments, Tyvek® 1073B 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® 1073B can maintain sterility for at least five years if package integrity is not compromised.

Key Benefits

Tyvek® 1073B provides a range of advantages for medical device manufacturers. These include:

  • Outstanding microbial barrier
  • High strength to weight ratio
  • Moisture resistance
  • Inertness to most chemicals
  • Air and water vapor permeability
  • Clean peel performance
  • Low linting due to continuous filaments
  • Puncture resistance for optimal protection during distribution and handling
  • Compatibility with many sterilization processes.
  • Production under ISO 14001, offering recyclability and support of sustainability programs.

Sterilization Compatibility

Unlike other materials, Tyvek® 1073B and all Tyvek® styles for medical device packaging are compatible with the most common methods of sterilization, giving medical device and pharmaceutical manufacturers greater flexibility. These include:

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

Reliable Supply

To meet growing global demand and ensure continuity and flexibility of future supply, DuPont has transitioned manufacturing of Tyvek® 1073B to production lines using the latest flash-spinning technology.
