If you manufacture food products in trays or pouches, your packages are just as important to your success, as the products themselves. That’s why you need to the best possible pouch seal integrity testing equipment you can buy. Here are some of the choices you have, when it comes to equipment.
How Package Testing Works
When you test food packages it’s important to test how strong the seal is, and the integrity of the package. These two testing procedures are not the same, but they are both necessary to make sure your food containers do not let contaminants inside. Even though pouch seal integrity testing is vital, the integrity of the entire package is just as important.
Leak Testing
Leak testing is used to test the strength of the package, and this is often done with a pressure decay test. The package is pressurized with gas, and then the difference in pressure is measured two times. If the pressure drops, then there is some kind of leak in the package or pouch. Which is sometimes called an inflation test because the package is inflated, with air!
Seal Testing
Testing the seal is very important because it prevents product tampering and spoilage. Inflation tests can be used for a wide variety of packages. For example, you can test pouches, trays, tubes, and laminated materials. One common pouch seal integrity testing method is destructive but very effective. It inflates the package until it bursts and this lets you know how strong the seal is.
Creep testing is also used. For this kind of test, the package is placed under constant stress, and the deformation is measured. This gives the tester the creep rate of the package. Creep to failure testing continues the test until the seal actually fails. You can contact leak testing professionals for more information on the subject.
