sealing properties of plastic films/ Hot- Tack- Test
Only suitable for flexible films. Preparing of sealings and testing by means of Hot-Tack- Tester (KOPP- apparatus) analogue ASTM F 1921.The tests are prepared by using pre-agreed parameters. To create sealing curves individual parameters are varied, e.g. for determining the dependence of the sealing properties on the sealing temperature Ts [° C]. Of course, sealing curves can also determined as a function of cooling time [ms], sealing pressure ps [N / cm], sealing time ts [s] or testing speed [m/s]. Typically, one parameter is varied over 5 equal steps and the results are plotted graphically as a function of the variable. (accredited test).

hot- tack (single point test)Select this item when you, for example, want to compare the hot-tack properties of two materials under specified sealing conditions. We then determine the hot tack seal strength based on n = 5 individual measurements under this parameter setting. If you are interested in the hot-tack properties e.g. as a function of the by the sealing temperature, please select "hot tack curve".
hot- tack- graph (as a function of sealing temperature)
The sealing tests were performed by varying of the sealing temperature. The parameters sealing pressure, sealing time, cooling time and testing speed are kept constant. The results are plotted as a function of the varied parameter. In general a hot- tack- graph can be prepared by varying other parameters too. Please feel free to contact us concerning this matter.
