HTT-02 Hot Tack and Tensile Testing Machine
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
Hot Tack Test Overview
The HTT-02 Hot Tack Tester, compliant with ASTM F1921 standards, stands out as a pinnacle of precision in hot tack testing. Employing a sample strip, the machine seals it under precise conditions of temperature, contact time, cooling time, and pressure using two flat heated jaws. The result is a meticulous measurement of the strength of heat seals formed between thermoplastic surfaces, offering insights crucial to industries ranging from packaging and food to medicine and beverage.
