Hottack tester Labormaster Impulse

Sealing strength tester Labormaster 3500

The Labormaster hottack tester has its permanent place in packaging material development for flexible packaging, i.e. for classic plastic films, laminates and composites as well as for coated papers or new sealable, recyclable packaging materials and compostable packaging materials.

During production, the Labormaster is used in the manufacture and refinement of packaging materials for quality assurance.

In addition, the testing device helps quality control and quality assurance in checking the sealing properties, heat sealability and in determining the optimal processing parameters (sealing window).

For impulse sealing tests with subsequent tensile testing (hot tack or cold tack) on sealable flexible packaging materials.

Fully digitally controlled
For measuring impulse sealing strength immediatly after impulse sealing (hottack)
For measuring impulse sealing strength after defined cooling time (coldtack)
Usable as a laboratory impulse sealer
Precisely adjustable, calibrated sealing parameters and test parameters – sealing time, sealing temperature, cooling temperature, sealing force (closing force), withdrawal time (cooling time after opening the sealing bars) and withdrawal rate (pull-off speed
The effective sealing force is measured for each sealing and the system automatically takes the thickness of the material of the samples into account
High accuracy and maximum reproducibility of all parameters
Meets all requirements of a test device according to DIN ISO
Display of the measured force as a graph
Test series with up to 10 curves can be displayed
Easy operation and clear presentation on the touch panel
USB and Ethernet interface for saving the test series
