Package integrity is of paramount importance in ensuring that sterility is maintained over a product’s entire shelf life. It is also a critical factor in preventing penetration of microorganisms throughout the distribution process. International Organization for Standardization defines package integrity as "the unimpaired physical condition of the final package."

Flexible pouches are extensively being used in the pharmaceutical and food industry as a primary packaging component. Even a minute breach in the sterile condition of the product is often considered a serious risk, resulting in the disposal of valuable products. Therefore, manufacturers give utmost importance for package integrity testing. Today, the market offers a host of techniques that can evaluate packages both destructively and non-destructively. In this blog we will discuss how VeriPac Flex system effectively evaluates integrity of a wide range of flexible packages.

Flexible package inspection using VeriPac Flex Series

Designed specifically for pouches and other flexible packaging with dry-filled products, VeriPac FLEX series are innovative non-destructive container closure integrity testing (CCIT) systems. Applicable across a wide range of flexible packaging formats, this technology provides unparalleled sensitivity, reliability and practicality in testing without requiring change-over of settings or tooling.

Utilizing the ASTM method for Vacuum decay leak testing (F2338), VeriPac inspection systems provide quantitative data and definitive PASS or FAIL results. PTI offers VeriPac FLEX Systems in several configurations to accommodate various package specifications and test sensitivity requirements. Such configurators for both the leak test instrument and the test chamber capacity enable evaluation of small format sachets and stick packs, up to large bulk size pouches and bags.

Because it eliminates subjectivity, reduces the waste and cost associated with traditional test methods, they are perfect alternatives to destructive package inspection techniques. Infact Vacuum decay leak testing technology has proven to provide a short return on investment when compared to destructive methods, such as the water bath or blue dye leak test. Listed in ISO 11607 and recognized by the FDA as a consensus standard for package integrity testing, VeriPac test systems detect critical packaging failures reliably and reveal valuable information on the packaging process.

Understanding the working of VeriPac FLEX systems

Depending on the size of the package, the test operator first connects VeriPac tester to the appropriate FLEX chamber. There are two VeriPac systems namely, integrated flexible test chamber (IFC) and drawer Style test chamber (D-Series) that can be paired with the FLEX chamber to provide different leak detection capability depending on the application. While the integrated flexible test chamber is for sachets or stick packs with low headspace, drawer style test chamber features two standard sizes, the Small (D) or Large (DXL) depending upon the package size and specifications. Customs designs can be manufactured for large package formats and bulk products. The unique difference with VeriPac FLEX systems is how the package is tested. PTI utilizes its flexible membrane that conforms to the package shape and size, eliminating any stress and damage to the film materials.
