SUPPLIERS of food in modified atmosphere packaging are faced with a sizeable challenge as retail stores continue demanding high quality. For these food suppliers this means that continuous quality control is paramount to avoid returned goods and a damaged reputation.
Witt Gas technologies have stepped in to enable suppliers to enhance their quality control. With speeds up to 15 cycles per minute Witts Markus Mertens believes that the companys new in line micro leak detection system ˜Leak-Master Inline is the solution.
Mertens said: It can be easily synchronised with the cycles of packaging machines and we believe this is the only leak detection system that can do this. With ˜Leak-Master Inline, most producing or packaging facilities can quickly test every product that is packed “ this is a significant benefit for quality management in the food industry.
The main factors influencing the speeds are the CO2 concentration in the package and the chamber size, explained Mertens. The gases used for products packed in a modified atmosphere usually include CO2, there are other products that actually give off CO2. The ˜Leak-Master Inline uses this CO2 as a trace gas, making it possible to test the newly produced packages for leaks directly after the packaging process.
