The use of flexible packaging films in food and other industries is vast. These flexible packaging films will work on the principle that when heat and pressure are applied to the packaging films, then they will form a bond between the two materials. This will make them inseparable from each other. Thus, you can easily test the heat sealing strength of labels with the use of a Testronix heat seal tester. This testing instrument comes with various advanced features with temperature controllers for both jaws of the machine, to make the seal testing even more precise. If you want to use this testing instrument for a longer time, then we suggest you go with the tips mentioned in this blog to maintain this amazing testing instrument.
