Testing Food Package for Leaks to Promote Safety

With the growing time, packaging food has become more popular. More people are buying this packaged food on a daily basis. Many processing companies have also come up bringing us this packaged food. The idea is great. However, food packaging is a complex process. It requires leak detection equipment to ensure the seal is efficient and effective.

One thing that everyone has seen is the “do not consume if seal is broken” label on all food packages. It is advisable to check the seal. However, the real danger is not with the broken seal. If the seal wasn’t installed well, it could have some leaks. Some of the leaks are invisible to the human eye. That, however, doesn’t make them safe. They could be harmful to you.

Leak detection equipment
These are equipment used in detecting any faulty seals. Their job is to test the package thoroughly to ensure it is super tight and is devoid of any leaks.

Types of leak detection equipment.
The equipment comes in different kinds depending on its specific functions; usually defined by the type of foodstuff being packaged. For instance, there is the equipment used for testing food packages containing food in liquid form while some specifically inspect the packages containing food in its solid form.

The technology used to detect leaks in packages containing liquid form is the underwater vacuum/bubble emanation technology. The package is held under water and observed at a microns level. If any bubbles are detected by the equipment, the seal is returned to be redone.

Food cans are also tested. The leak detection equipment at this point is used to pressurize the can. Air is pumped into it and then it is observed for any leakages. This process can also involve water. The can is held underwater to detect any bubble emission.

Purpose of leak detection
Food packages that have leaks can reduce the shelf life of the food inside. The fault line in a package allows air and other substances to enter the food package. In most cases, any foreign material that enters the package will cause the food to have a shorter lifespan due to contamination.

When someone buys food that has a leak, he or she won’t know immediately because he or she may be tricked by the expiry date. The expiry date is based on the maximum performance of the package. However, if the leak has contaminated the food, the date won’t accurately reflect the performance of the seal. Selling contaminated foods will lead to low reviews in case a customer is affected adversely by the foodstuff.

Leak detection equipment is also used to test if the food packages are fit for shipment. The inspection is advantageous to the manufacturer since it reduces the risk of losing products during shipment.
