What's a hot tack tester?

Hot Tack is the strength of a heat-seal immediately after sealing, that is, before it has cooled down and reached its maximum strength. Conventional testing with a separate heat sealer and tensile tester seldom correlates with the strength of a hot seal as it is first exposed to stress on a packaging machine.

The Hot Tack Tester has been designed for testing the heat seal strength under accurately controlled conditions.

The Hot Tack Tester is a highly sophisticated instrument for testing sealing properties of packaging material. It is being used in research and development as well as in Statistical quality control(SQC)/ Statistical process control (SPC) applications for raw materials; semi finished goods and finished packaging products.

The Hot Tack Tester permits evaluation of sealability and hot tack under a broad range of testing conditions to optimize packaging machine settings and to ensure consistent quality of the product.

The instrument is also a practicable and helpful tool to packaging material manufacturers and end-users for incoming material inspection and for obtaining optimal production line speed.
