For rapid determination of heat sealability of flexible packaging. Produces 3 or 5 independently temperature controlled seals, up to 15mm wide x 30mm long.

Precise control of heat sealing process variables (temperature, pressure, and dwell 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 HSG Gradient provides precision digital controls for this purpose. Fitted with either 3 or 5 sets of sealing bars with individual temperature controls to create a temperature gradient across the film.
