PTI White Papers

  1. Experimental Design And Positive Controls For Package Integrity 4/9/2020

    Given that the experimental design has only two conditions, leaking and non-leaking, this variable is extremely important to understand. Proper use of positive controls and knowledge of how alternative approaches are applied to challenge a test method support the validity and reliability of the method.

  2. Container Closure Integrity Testing: Sensitivity, Automation, Efficiency 4/6/2020

    Explore the need for sensitive, reliable, and automated container closure integrity testing technologies, and how existing deterministic solutions can help achieve optimum quality assurance goals.

  3. Dye Ingress For CCIT: A Poor Bet In A High Stakes Game 3/23/2020

    The dye ingress test method continues to be a widely used test method for container closure integrity. This paper explains why the dye ingress test method is not a suitable approach.

  4. Understanding Ultrasound Technology To Inspect Pouch Seals

    Traditional test methods of testing pouch seals are often destructive and can be unreliable. However, ultrasound technology offers a non-destructive means to ensure pouches are airtight.

  5. Understanding Pressure Decay Leak Testing For Bottles And Containers

    Leak detection of empty containers — before the filling and sealing process — is an important step to insure container integrity. Applications in the plastic, blow molding, food, beverage and pharmaceutical industries all require some type of online container integrity system.

  6. Container And Closure System Integrity Testing In Lieu Of Sterility Testing As A Component Of The Stability Protocol For Sterile Products

    The purpose of stability testing is to provide evidence on how the quality of a substance or product varies with time under the influence of a variety of environmental factors such as temperature, humidity, and light, which enables you to establish or modify recommended storage conditions, retest periods, and shelf life or dating period, as the case may be.

  7. Deconstructing The Blue Dye Leak Test Method

    Blister package manufacturing for tablets and capsules has process and material parameters that are unique to each product. Barrier properties of blister packaging are primarily designed to eliminate moisture ingress, a result of H2O molecules passing through micro leaks over extended periods of time. By Oliver Stauffer, PTI Packaging and Inspection Systems

  8. Blister Pack Leak Detection: Protecting Product Integrity

    The blister packaging process for tablets and capsules is unique to the packaging industry in so many ways. Blister packaging will always exist due to its practicality; but, the things that make blister packaging difficult to work with also make it a desired product presentation.

  9. Flexible Insights

    As more and more packages and processors convert to flexible packaging from more traditional forms of rigid methods including metal cans, PET and glass bottles or jars, they are confronted with the concern and challenge of how do they insure or equal the seal integrity levels from flexible packaging that they have come to expect from these more traditional packaging methods.

  10. Understanding Vacuum Decay Leak Testing

    The ability to detect leaks is necessary to ensure consistency and integrity of packages. It is also important to detect leaks and defects that are not visibly detectable. VeriPac's non-destructive technology is capable of detecting package leaks and invisible defects using an absolute or differential pressure transducer leak test system.
