Precision Laboratory Heat Sealer - for production of repeatable high quality heat seals. Precise control of heat sealing process variables (temperature, pressure, and time), enables an optimal balance of material specification, packaging machine speed and seal integrity. Accuracy and repeatability in laboratory heat seal testing is vital, and the HSE-3 provides precision digital controls for this purpose. Produces seals 5 – 25 mm wide and up to 300 mm long.
