Application
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.
Standards
ASTM F1921
Principle
A sample strip is sealed by applying pressure from two flat heated jaws under defined conditions of temperatures, contact time, cooling time and pressure.
