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.
C632B Hot Tack Tester is applicable in hot tack and heat seal performance tests for plastic films, laminated films and other packaging materials. It is applicable in peel test, tensile at break test, and other tests for adhesives, adhesive tapes, laminated films, plastic films, paper and other flexible materials.
i-Thermotek 2400 Heat Seal & Hot Tack Tester can be used for seal strength test after the seal immediately (hot tack) or waiting it cools to room temperature (heat seal). It can be used for plastic films, composite films and other packaging materials.
