Hot tack is the property of a heat-sealed layer to resist forces that would pull the seal apart while it is still hot. This
property is of vital importance for vertical form fill and seal process (VFFS). HTT-02 Hot Tack Tester measures the strength of heat seals formed between thermoplastic surfaces immediately after the seal has been made and before it cools to room temperature.
