Description
For sealing tests with subsequent tensile testing (hot tack or cold tack) on sealable flexible packaging materials.
- For measuring sealing strength immediatly after sealing (hottack)
- For measuring sealing strength after defined cooling time (coldtack)
- Usable as a laboratory sealer
- Precisely adjustable, calibrated sealing parameters and test parameters – sealing time, sealing temperature at the top, sealing temperature at the bottom, sealing force (closing force), withdrawal time (cooling time) and withdrawal rate (pull-off speed)
- High accuracy and maximum reproducibility of all parameters
- Exchangeable sealing bars with different surfaces (smooth, grooved, corrugated)
- Meets all requirements of a test device according to DIN ISO
- Displaying of the meassuerd 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

Datavis Visualzation for Labormaster
Softwaretool DATAVIS for Windows(r) has been designed for a quick and easy visualzation of the measurement data taken from the Labormaster. Test parameters and force/time curves of test series are displayed on the PC screen and can be printed.
Sample cutter
Manual cutter with two parallel cutting blades. Width 45 mm others on request.
Mobile trolly for Labormaster
to placeing the Laboratory Sealer SGPE or the sealing strength tester Labormaster
Cover hood for laboratory sealer

Sealing bar with silicone rubber for laboratory sealer SGPE and Labormaster
for sealing against metal bar (hard against soft). The silicone bar can be heated.
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 hottack tester Labormaster helps quality control and quality assurance in checking the sealing properties, heat sealability and in determining the optimal processing parameters (sealing window).
