Sealing
Seal strength & hot tack tester
RDM HT-2PC · ZwickRoell (ASTM F88)
We build the material’s sealing map: temperature, time and pressure, with the strength obtained at each point. Those are the settings you take to the machine.

What we measure
- —Seal strength (N/15 mm)
- —Hot tack — strength of the still-hot seal
- —Sealing window (temperature × time × pressure)
- —Failure mode: peel, delamination or break
- —Seals made at controlled time, pressure and temperature, for other tests
Where it is used
Topseal and flowpack packaging, bags, peel-off lids — and any “the pack opens” complaint.
