Seal seam strength tester Labormaster HCT 3000
The quartz sensor is delivered calibrated from the factory.
The seal seam strength is determined according to a test arrangement carried out by
finally torn apart.
The tensioning causes a system-related dwell time between the end of the seal and the start of the
separation process of approx. 0.240 seconds (at pull-off speeds of 0.2 to 12 m/
min., which corresponds to a seam separation speed of 0.1 to 6 m/min. The seal seam strength

The complete force curve of the tensile test is recorded, displayed as a curve and can be
evaluated.

Cold seam strength) along the sealing seam is shown as an absolute size in Newton.
Measuring device: clamped in the two clamps of the tension
measuring device. One clamp is connected to the
force transducer and the other is designed as a
rotating cylinder. Immediately after the sealing
process, the lower cylindrical clamp is
rotated and the piece of film is wound up. The seam
is pulled out of the heating area, tensioned
and
A highly sensitive quartz element (piezoelectric sensor) with a wide measuring range is used
to measure the force (sealing seam strength). The force creates an electrical voltage in the
experimental setup. The measured voltage is converted into Newtons. The measured
maximum value is shown on the display.
