Leak testing is a QA / QC test that is carried out on product packages to ensure that the packaging does not leak from holes inside the package or seal leaks that could end up damaging the product. Package Leak Detectors are used to detect problems after the packaging process to ensure seal integrity, ensuring both product quality and expected shelf life. 

Package Leak Detectors detect levels of leaks and holes within your package, allowing for an exchange of air between the package and the surrounding environment that can ultimately compromise product quality and desired shelf life.

Package leak detectors ensure seal integrity issues are identified. This is a vital part of the quality control of modified atmosphere packaging (MAP), as compromising the protective atmosphere will cause a reduction in the shelf life of MAP products.

Leak detectors increase production speed and minimize the risk of undetected package integrity issues resulting in unwanted returns and damaged customer relationships.

If the seal of a package is compromised, a leak will cause the loss of the protective atmosphere within the package and the shelf life of the product will be shortened, which could result in costly returns. Therefore, a package leak detector is a vital part of MAP's quality control.

Typical products where leak detection should be used are: vacuum chambers, TV tubes and other cathodes, hermetically sealed electronic components, pressure vessels, aerosol containers, vacuum thermal insulation (e.g. dewars), pumps, refrigeration systems, chemicals and nuclear plants, beverage cans, products containing metal bellows, electron microscopes, pacifiers, etc.
