Heat Seal Tester, Heat Seal Strength Tester

Heat seal test is to determine the suitable sealing parameters (sealing temperature, dwell time and pressure) for materials. ASTM F2029 is the standard practice for making heat seals for the determination of the heat sealability of flexible webs as measured by seal strength.

Hot tack is the strength of heat seals formed between thermoplastic surfaces of flexible webs, immediately after the seal has been made and before it cools to room temperature.
