Hot Seal Strength / Hot Tack Testing
ASTM F1921 - Standard Test Method for Hot Seal Strength (Hot Tack) of Thermoplastic Polymers and Blends Comprising the Sealing Surfaces of Flexible Webs
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. Hot Tack test makes it possible to determine the seal strength and appropriate sealing parameters directly after the heat sealing process.
