How does Airborne Ultrasound Technology Help in Testing Tyvek Packages?

How does Airborne Ultrasound Technology Help in Testing Tyvek Packages?

Tyvek is a highly durable and lightweight material that is commonly used in the medical industry for the packaging and sterilization of medical devices and equipment. It is a non-woven material made from high-density polyethylene fibers that are bonded together using heat and pressure. Medical device manufacturers and packaging professionals prefer Tyvek packaging because it is a sterile barrier that protects against bacteria and other contaminants. Tyvek is also breathable, allowing for sterilization methods such as ethylene oxide and gamma irradiation to be used effectively.

Tyvek packaging is used in a variety of medical applications, including surgical gowns, drapes, and covers, as well as in medical device packaging such as catheters, implants, and instruments. Its use in the medical industry is regulated by government agencies such as the FDA to ensure that it meets the necessary standards for safety, sterility and efficacy.

What are the Challenges Associated with Tyvek Package Testing?

Leak testing of Tyvek packages is a critical step in ensuring the integrity of the package and the safety of its contents. However, there are several challenges associated with leak testing Tyvek packages, including:

  • Sensitivity of the test method: The sensitivity of the leak testing method can impact the ability to detect leaks in Tyvek packages. For example, some testing methods may not be able to detect very small leaks or may be impacted by the size or shape of the package.
  • Environmental conditions: Environmental factors, such as temperature, humidity, and pressure, can impact the results of the leak test. For example, changes in temperature can cause the package to expand or contract, which can impact the tightness of the seal and the results of the test.
  • Interference with product properties: Some leak testing methods may use test gases or liquids that can interact with the product inside the package. For example, the test gas may cause the product to degrade or impact its efficacy, which can affect the overall performance of the package.

In summary, leak testing of Tyvek packages requires careful consideration of the test method, the packaging process, and the environmental conditions to ensure accurate and reliable results.

Testing Tyvek Packages Using Airborne Ultrasound Technology

With today’s sensory technology advancements, Tyvek packages can be tested using Airborne Ultrasound technology. Airborne Ultrasound technology is a seal quality testing method that uses airborne ultrasound to evaluate seals for flaws and defects non-destructively. It is an ASTM Test Method F3004 for testing the seal quality and a recognized FDA standard for seal quality inspection. These tests are mostly carried out to improve seal quality inspection of pouches, flexible packaging, and tray seals. Tyvek, paper, foil, film, aluminum, plastic, and poly are just a few of the packaging materials that may be used with Airborne Ultrasound technology to enable thorough seal quality evaluations.

In this method, sound waves are reflected as ultrasonic waves are transmitted through the packaging seal. If there is a leak or flaw, the signal intensity is decreased or lost. To find the leak, these differences are closely monitored. Most leak test techniques encounter the problem of being unable to identify non-leaking defects. By using Airborne Ultrasound technology, users may recognize a variety of seal faults, including visible and invisible, leaking and non-leaking, process-related and random. Airborne ultrasound can be applied in the laboratory for offline in-depth seal quality analysis as well as for 100% online seal quality inspection on the production line.

Benefits of Airborne Ultrasound Technology

  • Non-destructive, non-subjective, no sample preparation.
  • Deterministic inspection method producing quantitative results.
  • Can be integrated for 100% online defect detection of the final pouch seal.
  • Repeatable and reliable results.
  • Eliminates subjective manual vision inspection methods.
  • Characterizes overall quality and uniformity of the seal.
  • Economical cost-effective solution for seal integrity testing the final pouch seal.

The method used for leak testing Tyvek packages will depend on the specific requirements of the medical device or equipment being packaged and the regulations set forth by regulatory agencies such as the FDA. It is important to use a validated and appropriate method for leak testing to ensure the safety and effectiveness of the packaged medical devices or equipment. Airborne Ultrasound is one such technique.
