6 Types of Leak Detection for Food Packaging

If you produce food packaging, you need to make sure that it is secure. That is why you need to review the various kinds of leak detection equipment on the market today. Doing so will ensure the successful production of food products and will help maintain your customers’ trust. The following types of equipment can be used to detect leaks and prevent unwanted call-backs.

1. Ultrasonic Measurement Devices

This type of leak detection gauges leaks by measuring sound. A leaking food package often produces a high-frequency sound – one that can be easily detected by this type of device. This type of equipment detects leakage using a metre. It also allows you to know the rate of leakage. For more knowledge, Flexpak inc has more resources available for your reference.

2. Pressure Decay Equipment

Some equipment used for detecting leaks measures leakage by employing pressure. Any package that is intact should maintain pressure. If the pressure changes, it means the package should be repackaged or disposed of.

3. Vacuum Decay Equipment

Vacuum decay equipment is yet another type of leak detection equipment that is used a great deal by manufacturers. This type of equipment measures the pressure within the package. When this happens, it creates a vacuum – one where the technician can check for pressure variances. If the pressure changes, that usually means a leak has developed.

4. Helium Sniff Equipment

Helium sniff equipment works with packaging where the food has been packaged with helium. The sniffer equipment scans the surface of the package to detect the inert gas. If the sniffer detects gas, it proves that the package has sprung a leak.

5. Helium Spray Equipment

Helium spray equipment, just like helium sniff equipment, uses helium to find leaks in food packages. In this case, the detection equipment is used to spray a packaging surface with helium. A sensor on the equipment notes if the gas has been absorbed into the packaging. If it has, it means a leak has formed and the food will need to be repackaged. This type of detection equipment is considered ideal, as it works in regular atmospheric conditions and senses leaks well.

6. Bubble Test Detection (by Consumers)

Whilst this test does not use a special piece of equipment, it still can help you detect leaks at home. Just submerge the package in water and check to see if any bubbles form. If you see the tell-tale bubbles, you cannot use the food. You can use this method often to avoid using foods that have spoiled or which have been negatively affected because of their poor packaging.
