In-line Non-destructive Leak Testing of Packs in Trays and Sealed Cartons

Fully automated, end of line and non-destructive leak detection system. Very sensitive. Uses the CO2 in the pack as a trace gas to detect micro-leaks.

Eradicating micro-leaks is essential for ensuring that the stated shelf life of products is reach. Even a pack with a single extremely small leak will have it’s gas flushed headspace returned to atmosphere within a few days. Real time quality information enables immediate intervention by site engineers / operators to address the cause of the leak and progressively improve packaging performance and overall equipment effectivenes (OEE).

Supplied with either manually fed, or fully automated conveyors for testing up to 4 cases, or trays, of packed product per minute. The LeakMatic II system has been designed to test several cartons, or trays, in one cycle. It is therefore possible to test all packages within moments of them being produce.

The progressive optimisation of the packaging process and the reduction of waste, or returns and of rework, all combine to give a fast payback on investment.

Process  Trays, or cases of packages are placed inside the Dansensor LeakMatic II test chamber and a user-defined vacuum is created. The vacuum produces a pressure difference between the inside of the packages and the test chamber, causing CO2 from the package to escape into the test chamber, even through the smallest leak.

Two highly sensitive CO2 sensors measure the difference between the %CO2 of the chamber and the atmosphere. A difference in %CO2 of 10-12 ppm indicates a leak. The alarm is activated and the carton /tray is automatically rejected.

Delivery, Installation and Training  All deliveries include initial site survey; factory acceptance test (FAT); delivery; installation and training; post-installation optimisation and refresher training.
