ASTM F1921 METHOD A HOT TACK TESTER tests the strength of heat seals formed between thermoplastic surfaces of flexible webs, immediately after a seal has been made and before it cools to ambient temperature.
Hot seal strength tester Hot tack tester principle
Hot seal strength tester automatically heatseals a specimen and immediately determines strength of the hot seal at a precisely measured time after conclusion of the sealing cycle
Test Standards
ASTM F1921: Standard Test Methods for Hot Seal Strength (Hot Tack) of Thermoplastic Polymers and Blends Comprising the Sealing Surfaces of Flexible Webs
