No matter what method or leak detection equipment is employed, useful information can be gathered that helps steer the course of design and materials acquisition that lead to the best and most affordable packaging solutions. Below are six ways that leaks can be determined.
1. Gas Leak Detection
Gases like hydrogen, carbon monoxide, and helium are added to the packaged products to see if leaks exist in food packaging. The equipment used in this process is highly sensitive and can determine any weaknesses in the containment materials and design. It’s considered a perfectly safe way of detecting leaks for food products.
2. Vision Testing By Machine
Visual leak testing is done by using a sensitive camera that is hooked up to a computer. It can determine even the smallest leaks or compromised seals with pinpoint accuracy. One benefit of the visual method is the ability to go at an individual pace and conduct a customized method of inspection that gets as specific as necessary. It can concentrate on specialized areas of seals and closures that are prone to leaks and failure.
3. Ultrasonic Testing
Ultrasonic methods of leak detection use sound waves and the disruption observed in order to determine the presence of flaws and failures. All you have to do is place the packaged items near a transducer and allow the waves to create a picture. Any breaks in the sound waves point to the exact area of weakness or a possible leak.
4. Immersion Testing
Bubbles provide the tell-tale signs of leaks when using the immersion leak testing technique. It also allows for determining the actual strength of the sealed areas of product packaging, which is critical before transporting by plane. You may be able to learn a lot more information from the Flexpak inc website and their online resources.
5. Dry Chamber
Placing liquid packaged products into a dry chamber and adding an absorbent material will provide trustworthy results. If the material addition results in no liquid found, the packaging is intact. Any fluid release demonstrates that the product cannot be shipped to customers. The product will have to be disposed of and any problems in the design or materials worked out.
6. Vacuum Chamber
Vacuum chamber leak testing is necessary before airplane transporting. You will be able to determine whether the packaging is able to withstand the pressure variances with air transport using this type of leak detection equipment. It’s considered a reliable method of determining the strength of the packaging materials.
A variety of leak detection equipment is available to help ensure that all food packaging provides the safe protection of items from manufacturing to market.
