Companies that sell packaged items face leakage issues every now and then, which can often lead to monetary losses. However, with the help of cutting-edge package leak testers and advanced testing methodology, it is possible to spot leaks quickly and ensure your food items and pharmaceutical products remain unaffected.

Investing in a package leak detector assures you that the integrity of your containers and the product within remains intact. The system is ideal for different products and is prevalent in the pharmaceutical and food industries. This article explores various testing methods you can employ today to check for leakage in your product effectively and earn a good reputation.

Methods to Test the Integrity of Package Seals

Leak testing is a quality control measure used to identify imperfections in manufactured products through porosity testing. Leakage tests for packaging will ensure that the product container offers strong protection.

Let us now take a look at a few methods of testing package leakage:

Vacuum Decay Method

Vacuum decay is a compelling package testing method to determine the leakage by creating a vacuum around the container. It involves putting sample packages inside an evacuation chamber that uses an external vacuum source to reduce air pressure around it to detect leaks. It is one of the most flexible and versatile testing methods that help maintain the quality of the package, ultimately reducing waste.

Bubble Emission Test

Bubble leak testing verifies the reliability of the sterilized barrier system. In bubble leak testing, the tester applies pressure to the container while it remains submerged in water. The tester then examines for any stream of bubbles which would signify a failing zone.

Dye Penetration Testing

Dye penetration testing analyzes the durability of seals and searches for flaws between components, like ruptures or channels within. The system keeps the dye on for a specific duration. That way, seal integrity examination becomes much more manageable.

Seal Strength Test

This method is a standard testing procedure for flexible barrier materials. As the name suggests, this method evaluates the strength of seals. To perform this test, a one-inch sealed part of the package must have both sides held inside grips placed in opposite directions, and then one side of the seal is pulled at a defined speed from the opposite side.

Ultrasonic Seal Test

This non-destructive method employs ultrasonics for a rapid assessment of the packing before a more in-depth evaluation. In this standard method, leaks produce a high frequency that, when recorded, can pinpoint the precise position of the leak. This technique also helps find contaminants near the seal.

Why Are Non-destructive Leak Testing Methods Crucial?

While leak testing is essential, it is also a priority to conduct the test without damaging the product contained within the packaging. Businesses can accomplish this by using non-destructive testing methods that ensure proper packaging evaluation without compromising the product inside. These non-destructive methods bring a couple of benefits to the table.

  • Saves substantial time and money: Manual leak testing relies on underwater submersion of the package, which can damage the content within the container. Additionally, the method is prone to errors resulting in the process taking more time and money. Contrarily, non-destructive leak testing methods like the vacuum decay technique are more straightforward and highly reliable.
  • Automation reduces error: Human error is a risk inherent in leak testing by hand. With non-destructive leak testing methods, the chances of error reduce since the procedure is fully automated.

Wrapping Up

Leak detection is essential for the food packaging and pharmaceutical industries to maintain the highest quality of items inside a sealed pack. Poor packaging and physical breach, like a leak, affect products’ quality, making them unfit for consumption. Hence, for consistent and cost-effective leak testing, top firms rely on package leak testers like the ones we produce here at Seal-Check to safeguard their products. Seal-Check is the premier leak testing partner for renowned players in the packaging industry.
