Proper food packaging is crucial when you want to maintain the freshness, authenticity and a good name as a manufacturer. To achieve perfection in food packaging, it must undergo tests to check whether it is compromised. These tests must be done often to ensure evaluation of food products packaging is faultless to save the manufacturers plenty of losses since food leakages can tarnish the reputation of the company. Getting the problem fixed through acquiring the right leak detection equipment and following required measures will enable manufacturers to avoid unanticipated costs. The following are major five techniques used in checking leakage in food packing.
1. The Ultrasonic Measurement
Leaks produce sound, which corresponds to their sizes and the tune produced by the hole can be high or low. Therefore, small leaks usually produce a sound with high frequency than large ones. Applying the ultrasonic detector gadget will detect the sound intensity and identify the rate of the leakage.
2. Bubble test
This technique is the most appropriate in test leakage in products, which have air in the packaging. It entails submerging packaging materials in water. If bubbles emanate, then there is the presence of leakage. Any product with such a fault should not be released into the market as they can be a menace to your financial significance or even implication. Bubble emission test can be harnessed to test any packaging material to determine, which point is burst.
3. Altitude Simulation Method
This marks one of the most leak detection equipment technique to test leaks in food packaging especially products shipped through the air. The method allows manufacturers to know the safety of the food packages to ensure they will not break in high altitudes while in the air. Since you will not carry out the test in the craft on motion, you are required to harness a vacuum chamber to observe the differences made.
4. The Gas Leak Detection Test
It entails the process of identifying leaks on the sample product you want to measure. It marks one of the most effective methods of testing leaks in large-scale production. This test can detect any openings in the food package. It can also be combined with dry chambers to trace gas leakages. It is involved with gases such as hydrogen, carbon dioxide, and helium.
5. The Dry Chamber Method
This is one of the most appropriate methods applied by most packers and food packaging industries to seal products such as milk. Dry chamber technique involves having food products placed in the chamber for testing and put in the vacuum. The essence of the process is drawing the vacuum chamber in the way of exposing the absorbent product packaging material. It is suitable for liquid foodstuffs like beverages.
