How Is Package Integrity Testing Carried Out?

Package integrity testing is critical to determining the sterility and shelf life of a product. Components of package integrity testing include vacuum leak, bubble leak, and other sterile barrier integrity assessments.

You can test for leaks in sterilized medical device packaging and other packaged items using dye penetration tests. The injection method is the most popular method of dye penetration testing. You can also get more facts on package integrity testing through

The dye solution is injected along the longest edge of a package, to a depth 1/4 inch. The transparent side of the package allows you to visually inspect the sealing area after administration of dye.

The technician will easily detect any channel on the seals in five seconds. This process is then repeated for the remaining sides of the pack. This test is carried out in accordance with ASTM standards.

Peel strength testing ensures your packaging is able to provide (and maintain) a sterile barrier for your product by evaluating the packaging for seal failure modes.

To perform the peel strength test, the seal test samples are prepared by cutting strips of packaging material so that the edges are well cut and perpendicular to the direction of the seal.

The sample's sealed area is placed between the grips of a tensile tester machine. This ensures that the seal line is parallel to the direction tension. The seal is then tested until it fails at a fixed grip separation rate.

The maximum force encountered when the sample is stressed to failure is recorded and the failure mode is recorded. Both the peel force and the seal strength can be determined depending on the seal failure mode.
