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