Over the years, food safety and quality has been a growing concern among the population. It is embarrassing, and potentially fatal, for any brand if a consumer purchases food only to find it spoiled due to leaks in the packaging. Thus, leak detection is of extreme importance. There are a number of machinery that can help in this task.
MediTest Vacuum Test
The vacuum test is a form of non-destructive testing. The test relies on the reactive force generated by each package during scrutiny under vacuum. The change in force lets the machine know if there are any leaks or holes in the package. This test takes only a few minutes to administer and can detect holes down to ten microns. The MediTest machine perform this test quickly and reliably.
MediBlue Methylene Blue Dye Test
The Methylene blue dye penetration test is an industry standard in leakage testing. It involves submerging the packaging in a solution containing methylene and placing the chamber in vacuum. If the packaging is faulty, the dye is forced into it and blue color of the dye makes the leak abundantly visible. Thus holes are quickly detected and the faulty package is discarded. MediBlue can automate this test.
The JLS PIVT system is a collection of technologies including vision, vacuum, sensors and more that can quickly and effectively detect leaks in packs and discard items that do not meet the industry standard. Producing over a 180 packs in under a minute, the technology can even provide statistical analysis to ensure comprehensive knowledge.
FlexPack’s Bubble Detection Test
Like the methylene dye test, the Flexpack Leak Detector submerges the packaging in a chamber filled with water and subjects it to vacuum. For packages with leaks or holes, air can be seen escaping from the package in the form of bubbles. Thus a simple visual inspection is enough to reject it.
MAPAX LD Inline Testing
The inline testing method offers real time testing data and hence is of immense value. It works by adding a small amount of hydrogen into the atmosphere during sealing phase which is then detected in the leak detecting phase. If there is any leak, the hydrogen gas will escape and the high caliber sensors will detect it in the atmosphere.
