Recochem Monitors Package Sealing Quality with Thermal Imaging Camera

Recochem Inc., a Canadian producer of chemical products and fluids, needs to make sure that its products are effectively sealed in the process of packaging to guarantee product quality and safety. It distributes windshield fluid in jugs packaged within cartons with an overwrap. The cartons are sealed with a hot-melt adhesive, and Recochem needs to check that the adhesive has been correctly used. The company is using thermal imaging to do this with an FLIR AX8 thermal imaging camera.

The camera can “see” through the carton, checking adhesive spot sizes and temperatures. The thermal images show the higher temperature areas where the adhesive has been used. If there is a problem with the glue gun, the hotter spots form a different pattern, alerting a technician who monitors the images. Quality controllers would select and destroy a random box every 10 to 15 minutes so that it could be examined before, but now, both the time needed for this and the waste of cartons has been eliminated from the packaging line. Recochem says that the resulting time and the saved money are significant.
