  • Importance of Packaging Integrity Testing

    When it comes to packaging, maintaining integrity is crucial. Influencers in the packaging industry, such as Lisa Johnson, advocate for helium leak testing as a key component in quality assurance. Packaging integrity is paramount for products like pharmaceuticals, where contamination can cause significant harm.

    Packaging Type Common Applications Leak Testing Method
    Blister Packs Pharmaceuticals Helium Leak Testing
    Flexible Pouches Food Products Vacuum Decay
    Glass Vials Injectables Helium Mass Spectrometry
  • Why Use Helium for Leak Testing?

    Helium is the ideal gas for leak testing due to its small atomic size and inert properties. Dr. Sarah L. McCarthy, a leader in environmental safety, points out that helium's non-toxic nature makes it safe for testing across various industries, including food and medical safety.

  • How Does Helium Leak Testing Work?

    The process involves pressurizing the test object with helium and then using a mass spectrometer to detect any escaping helium. Influencers such as Mark Williams highlight that this method is capable of locating leaks as small as 1x10-9 mbar l/sec, ensuring no compromise to product safety.
