Step 2 : Check the oxygen level – inline and as sample test
Gas analysers are essential for quality control . The checks can be done either as a continuous analysis directly during the packaging process , or following the packaging process as sample testing . Ideally , you would combine both methods .
For continuous analysis , a gas analysis module is integrated into the gas mixing system . The gas analyser continuously monitors the correct composition of the gas mixture . This ensures the correct gas mixture inside your packaging .
Incidentally , if you use a flow packer , you can even save gas and money with an integrated gas analyser . The gas supply is automatically reduced as long as the measured oxygen concentration is below the set limit . You only use as much gas as is essential for the optimal packaging result .
Sample gas analysis is widely established as a means of quality control . A needle is used to take a sample from the packaging . High-quality gas analysers such as the OXYBABY ® from WITT are extremely precise and fast and require only a very small amount of gas . Thus , they are also suitable for packaging with a very small headspace . The OXYBABY ® is one of the most widely used measuring instruments worldwide . The special feature : the needle is integrated into the housing . The OXYBABY ® can therefore be operated with one hand and is ideal for the mobile packaging test .
Step 3 : Don ’ t forget package leak testing
Leak testing is the important third step . As an entry-level solution for leak testing , the LEAK-MASTER ® EASY from WITT is a very simple but highly effective device . The product comes into a water-filled chamber .
By means of compressed air , the air space above the water level is evacuated . Due to the resulting pressure difference , air or protective gas escapes at leaks and pearls up visibly . The big advantage of this method : the quality tester can easily see where the packaging is leaky .
The highest level of safety is offered by inline testing done by the LEAK- MASTER ® MAPMAX . The MAPMAX is integrated into the packaging line and tests the entire production output using CO2 sensors . It makes sense to focus on the detection of CO2 , as this gas features in most inert gas packaging .
Up to 15 test cycles per minute make the MAPMAX unique worldwide for this type of leak test . In addition to single packs , you can also check outer packs and entire boxes .
Just three steps to consider , and you will get perfection in modified atmosphere packaging .
