5 Methods used to Detect Leaks in Food Packaging Material

Many people are always reluctant about changing or inspecting the food packaging material they use when they are off to the grocery. While this is true, food packaging materials should be checked for leaks to ensure you don’t run into havoc.

However, consumers must rely on the lead detection equipment to detect any form of leaks in their food packaging equipment. You should also know that the leak detection method used by the manufacturers is not always 100 percent correct. Food poisoning, in some cases, emanates from leaks in the food packages because it can come into microorganisms that contaminate the food. The consumer must always be aware of the equipment and method that can be used to detect leaks in food packaging material to solve this problem.

Let us look at the following methods used to test leaks.

1. Ultrasonic Measurement

As a consumer, you should know that all leaks produce sounds related to their size. The sound’s frequency can be low or high depending on the leaks. Small leaks always produce a higher frequency. Therefore, you can make use of the ultrasonic leak detector to detect the high-frequency sounds from the food product packages. The ultrasonic leak detectors are small, hand-held gadgets that that are accompanied by a meter, a pair of headphones, and a sensitive adjustment nozzle. You can easily measure for leaks in the food packaging material for any leaks found. Also, the leaking rate of the material can be identified by the leak packaging material.

2. Bubble Test

Unlike the previous method that makes use of the ultrasonic measurement, this method uses a simple application. If you suspect any leakage of the food product package material, the package will be pressured by the customer. In the end, you will also submerge it in the water. If you see any form of bubbles from the water, it is clear that there are leaks. The rate of bubble development denotes the leak extent.

3. Pressure Decay

According to some laws in the scientific world, the leak packaging material pressure reduces the internal object pressure. Before you test for any leak in the package, therefore, the material must be changed using some amount of dry air such as nitrogen at that dry level. You will monitor the temperature for some time. When the material pressure comes down, it confirms that the food packaging material shows some leakages. Because it is simple, reliable, and compact, many people prefer using this method. Also, the method is relatively free from bias and cheap.

4. Vacuum Decay

When you talk about the vacuum test, you are talking about the opposite of the pressure decay method. It also involves the evacuation of the package material parts. This means you stabilize its pressure. You measure any form of pressure building up in the packaging material. However, not any packaging material can be subjected to this measurement. Therefore, you must work to develop certain conditions for certain types of material. Because you can’t affect it by any form of temperature fluctuations, the food packages can survive in a vacuum. This is one of the best methods used in identifying sensitive leaks as the best leak detection equipment.

5. Helium Sniff

For this procedure to amount to effectiveness, a helium sniffer can be used as a leak detection equipment to determine the occurrence of leaks in the food package material. The pressure of helium is directed to the food packaging material with enough force. You scan the surface for any helium leaks using the helium sniffer. The concentration of helium in the area will increase if the surface leaks. This is an efficient method as it identifies the leak location.
