Leak testing is a wide discipline that includes many different methods to determine seal integrity in order to ensure product performance and food packaging safety. Leak detection methods can generally be categorised as non-quantifiable versus quantifiable. 


Quantifiable Leak Detection Methods

Quantifiable methods are becoming the standard, given that these leak detection methods can be easily incorporated into online quality control systems. Today's manufacturing environments are driven by data and manufacturers rely on important data trends, including leak rates, repeatability, and rejection percentages in order to improve packaging design.


Modern leak testing methods are driven by data and provide results that can be used to detect very small changes in pressure. In addition, they can provide results very quickly and that are highly accurate. Manufacturers are employing the leak detection techniques that maximise accuracy, allow for data collection, and reduce overall costs.


Mass flow testing is a technique that has recently become popular. This method involves creating pressure within the product to be tested and then making use of a flow measurement transducer in order to measure the amount of airflow that is required to maintain the pressure, which results in a determination of the true volumetric leak rate.


Non-Destructive Packaging Testing

In addition, the non-destructive packaging testing is also becoming increasingly important in order to reduce waste caused by leak testing, and also to allow passed products to be returned to the packing line.  


Leak Tester Advances

Today's leak testing equipment can perform more functions than simply leak detection. They are also capable of collecting additional data, such as the measurement of force and temperature, to create a leak detection machine that adds overall value and decreases the amount of space required for the setup of leak detection testing equipment.


In addition, advances in data storage capacity are allowing users to capture data points beyond the simple pass or fail results. These testers can perform statistical analysis, display data, and provide updates in real time. This allows manufacturers to respond more quickly and make adjustments based on the data that is supplied by the leak detection equipment.


Leak testers are now offering increased memory capacity, allowing them to store more programs so that users can create test sequences and change test parameters more easily.


With the improvements that have been seen in the electronic components of leak testing equipment, manufacturers have been able to develop user-friendly features, such as touch screens and other controls. The instrumentation is also seeing some advancements with the latest leak detection systems delivering higher performance and more options for communication protocols.
