ASTM F1921 complied 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.
Principle of ASTM F1921 complied hot tack tester : A sample strip is sealed by applying pressure from two flat heated jaws under defined conditions of temperatures, contact time and pressure.
