Test food packaging for leaks inline

The LEAK-MASTER® MAPMAX from WITT enables food producers to ensure the quality of their packaging and thus their products: every package is tested inline – fully automatically, non-destructively and reliably.

Safety for the entire production process – directly on the line

The MAPMAX tests individual packages, complete sets, outer packaging or cartons on the packaging line – quickly and without contact. The CO₂-based test in a vacuum chamber detects even the smallest leaks from approximately 20 micrometers. Depending on the relevant leak size, CO₂ content in the packaging and other environmental parameters, a testing speed of up to 15 test cycles per minute is possible. This combination of sensitivity and speed makes the system unique and powerful enough to test the entire production output. Food producers thus achieve maximum safety and can give their customers a promise of quality.

Optimized for practical use

A vacuum creates a pressure difference that causes CO₂ to escape from leaky packaging. The flow-optimized machine design directs the gas to highly sensitive infrared sensors with a resolution of 1 ppm in a fraction of a second. This ensures that every leaky package is detected before it reaches the customer.

The test is non-destructive, which means there are no rejects, repackaging, and additional costs. In the event of a leak, the system communicates with downstream systems via potential-free contacts – for example, to trigger an alarm or activate an ejection system.

New design, easy to use

The current generation of MAPMAX has been specifically redesigned: the transparent acrylic glass design improves visibility of the process, the slimmer design saves space, and the optimized construction facilitates servicing during operation. Operation is intuitive via a touch display, and presets can be quickly called up or individually adjusted. An Ethernet interface is available for digital quality assurance.

The LEAK-MASTER® MAPMAX has proven itself over many years as a reliable inline system for leak testing. With the latest update, it now offers even greater practicality – while maintaining the same high level of testing accuracy. The unique combination of speed and sensitivity makes it the ideal solution for inline testing of entire cases, cartons or individual packages. This gives food producers maximum security: to protect their products, comply with delivery contracts and ensure customer satisfaction, says WITT.
