Touch Screen Precision Hot Tack Tester for determining the hot tack seal strength of flexible packaging materials. The HT-1SX seals and then immediately measures the peel strength of the hot seal. An intelligent controller and touch screen user interface provide test setting options, and allows multiple settings to be stored for later recall. Resulting graphs and data of load v time and load v temperature can be viewed, printed and exported to spreadsheets / SPC systems. Touch screen precision hot tack tester for determination of the hot tack seal strength of flexible packaging materials, to ASTM F1921.
