Why is Hot Tack Test Important?
After completion of the Hot Tack test you simply need to measure the length of the remaining (non-split) sealing seam and document the result. An optional Microsoft® Access based Software enables you to document your test results with a click of the mouse. The whole procedure – from testing to documentation – is only a matter of a few minutes.3.1.11.1 Discussion—The desired outcome of the test is to peel apart the seal formed by the test instrument. Other types of film failure in the tensile phase of the instrument test cycle may not represent hot tack strength. 3.1.12 hot-tack curve, n—a plot of measured hot-tack strength versus sealing temperature at fixed dwell time andFeatures as computerized testing parameters, can be easily set by just retrieving a desired parameter file, are common to all our testers.
