Leaks in food packaging are an incredibly serious problem for two reasons: they are usually undetectable to the naked eye and a leak in packaged food helps bacteria grow. That, in turn, can lead to food poisoning and nobody wants that. But if you are unable to see if your package of food has a leak (though you suspect it might), how can you make sure? Well, that is where leak detection equipment comes in! There are variety of methods by which to detect whether or not your package of food has a leak in it. In this article we will look at four of those methods. Remember: if you are worried that your food package has a leak, get it checked right away. Food poisoning can be fatal.
1. MEASURE ULTRASONIC SOUND WAVES TO DISCOVER PACKAGING LEAKS
When there is a leak in a package of food, that leak will most likely emit a high frequency sound that is undetectable to human ears but will be easily picked up by an ultrasonic measuring device. This type of leak detection equipment can find leaks in your food packages and give you important information on the amount of leakage.
2. SPRAY HELIUM OVER THE FOOD PACKAGE
This one might sound a little weird at first, but you don’t have to worry - it works and it works very well. Helium spray might in fact be the best way to discover leaks in food packaging. The process is simple: helium is sprayed over the section of packaging that you believe contains a leak. A sensor will then tell you if any of the helium has seeped into the packaging. If it has, you can be sure that a leak has developed in the packaging and you will need to take the appropriate next steps.
3. MEASURE THE AMOUNT OF VACUUM DECAY
Another piece of leak detection equipment is a device that measures vacuum decay in a package of food. When you use this device, it will create a vacuum that you can then measure over several hours or days to see if the pressure decreases or stays the same. If the pressure decreases over time, you can be reasonably sure that there is a leak in your packaged food.

4. SUBMERGE THE SUSPECT PACKAGE OF FOOD IN WATER
This leak detection method, unlike the previous three, does not use commercial leak detection equipment to see if there is a problem. Instead, the total submersion leak detection method (also known as the bubble leak method) is one that you can do at home with nothing more than the package of food, a deep enough bowl, and some water. To conduct this experiment, simply submerge the package of food in a bowl of water and watch closely to see if bubbles emerge from the package. If you see any bubbles, there is definitely a leak and the food will have to be thrown out.
