4 Methods for Leak Detection in Food Packaging


There is no doubt that every product needs to have the best packaging to protect the food from getting germs. The product packaging must go through a test to identify if there is any defect. Testing food product packaging for any product will save manufacturers a lot of money in the end. Food product leakages can be very costly. Therefore, it is necessary to test the packaging to save money. Investing in leak detection equipment is the best choice for manufacturers. Manufacturers of packages need to check for the irregularities. In doing so, it will prevent the food from going bad. The leak detection should take place before the food goes to consumers. Here are four primary methods for leak detection in food packaging.

1. Altitude simulation technique

It is suitable for testing leaks in products that travel through the air. The altitude simulation technique helps prevent products from collapsing when in high altitudes. As such, the manufactures will save money when the product arrives at customers in good condition. One cannot use this method to test for products while on air. Therefore, a vacuum chamber comes in handy to test if the product can survive the high altitudes while they are in transit.

2. Gas leak detection

This method is suitable for tracing small openings. It is an effective way to detect leaks in food packaging. In addition to that, it is appropriate for testing gas detection. Some of the gases that undergo the test under this method are hydrogen, helium, and carbon dioxide. The gas leak detection method is an effective way to determine where there are gas leakages.

3. Bubble emission test

The bubble emission testing is appropriate for testing leakages in foodstuff that contain air. The product undergoing trial goes into the water. In case the product packaging produces bubbles, then it means that the test is positive. Therefore, such a product should not go to the market. Manufacturers of packages will save money since they will not sell a product that has a defect. You should visit the FlexPak website if you would like more information.

4. Dry chamber method

Manufacturers of packages use the dry chamber method to test leaks in liquid products like milk. It makes it easier to find out if the product is leaking. The foodstuff packaging goes to a chamber, and then it is set in a vacuum. The material used is an absorbent one. The test is positive when the foodstuff packaging produces any liquid.

Product packaging is an important part when dealing with foodstuffs. However, the packaging has to meet the set requirements. Without the leak detection testing, the product may not provide customers with the services they require. Therefore, manufactures of packages can choose any of the above methods to determine whether the product is in good condition or not.
