Package Integrity Testing
What is Package Integrity Testing?
Package Integrity Testing is the evaluation of packaging to meet the desired amount of protection or containment of the packaging components. The physical capability of the packaging is evaluated to measure the protection of the package’s contents. This is performed by measuring: microbiological, chemical, product, and barrier attributes. Testing for package integrity provides assurance that a package is sealed properly, the product within is contained, and foreign contaminants remain outside the packaging system. In the long run, testing for package integrity will save your company thousands of dollars from potential defects or failures later on. It is important to make sure your packaged product is capable of handling the conditions it will face along the way.
How To Test for Package Integrity
Dye Penetration Package Integrity Testing is a destructive package integrity test that is applied to a transparent material that has been sealed to a porous material. A dye solution is injected into the package along the longest edge of the inner seal. Once the dye has been injected, a visual inspection is performed looking for channels of dye dispersed across the package’s heat seals. Potential defects within the seal of a sterile barrier system can then be visually assessed using this type of testing. There are three different dye penetration methodologies with Method A being the preferred testing methodology.
Method A – Injection: The dye solution is injected into the package along the longest seal edge and the seal is inspected for channeling or leaks.
Method B – Edge Dip: The edge of the package is physically dipped into the dye solution and then observed for any wicking upward for any channels.
Method C – Eye Dropper: After separating the two materials, an eye dropper is used to place a bead of dye solution along the outside edge of the package seal to detect a channel in the seal.
The ASTM standard used for dye penetration testing is ASTM F1929 – Standard Test Method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration.
