Composite Film Heat Seal Strength and Hot Tack Tester

Measures seal strength immediately after sealing, and sealing temperature windows for laminate films. Used for packaging line setup of pouches and form-fill-seal films. Data helps set sealing temperature and dwell for high-speed packing lines.

Specification

Sealing bars with precise temperature, pressure and dwell create seals which are pulled while still hot. The graph of hot tack force versus temperature shows the processing window of the film.
