5 Ways Leaks Are Detected in Food Packaging

Ensuring the integrity of food packaging is essential. When it comes to keeping your food safe to eat, it takes a lot of vigilance to maintain proper safety standards. When food packages are leaky, they can become contaminated, ruining the contents of the package and potentially making people sick. To avoid these sorts of issues, professionals use leak detection equipment to make sure that the packages are safe.

All of the equipment used to detect leaks is very good at making sure that the packages are as secure as they need to be. Not all of this equipment operates in the same ways, though. There are different methods for detecting leaks that are only used with certain pieces of equipment. Learn about five of the most prevalent ways these leaks are detected below.

1. Bubble Testing Method

This method is really simple when you get down to it. The fact that it is simplistic doesn’t mean that it isn’t effective, though. When testers think that there may be a leak in a package, they will put it underwater. If bubbles come rising to the surface, then it confirms that there is something leaking from the package itself.

As far as leak detection goes, this certainly isn’t the most elegant method. It’s a commonly used method because of low cost and ease of use.

2. Spraying with Helium

This method can be a bit tricky to use. You need to separate a section of the material from the packaging that you’re trying to test. Using a special pump, helium is inserted into this void. If there are leaks, then the helium will penetrate parts of the packaging. There is a detector capable of measuring the helium, giving you accurate data on how bad the leak is.

This is a much more professional method of leak detection that is used by many companies. The hardest part of the process is separating the section of the material so you can pump the helium in. Once that is done, this is a very reliable method that you should make good use of.

3. Sniffing Equipment Using Helium

Another method that uses helium is sniffing equipment. This can be very effective, just as the spraying method. Helium is placed into the food packaging and sniffer detects for leaks. It’s simple in concept and will easily tell you if the package is leaking anywhere. The sniffing device is quite sensitive so it can pick up on even a minute leak.

4. Measuring Ultrasonic Sound Waves

A very common leak detection method is to measure the contents of a package using ultrasonic sound waves. The equipment involved in this process is incredibly sensitive so it will be able to give you good leak data to use. Using sound detection to see if there are any tiny leaks in the packaging will be simple to learn how to do. You’ll even be able to get data on how fast things are leaking out of the package.

5. Measuring the Rate Pressure Decays

The final method is to measure the rate that pressure is decaying within the package. The presence of a leak in the package changes how much pressure there is inside. Putting something such as dry air inside of the package will allow a device to measure the rate the pressure decays at. You can get simple but accurate data using this technique.
