Hot tack tester/Heat Seal tester

Product catalog summary

Overview: The document provides technical details about the LABTHINK HTT-L1 Hot Tack Tester, a device used to measure the strength of heat seals in thermoplastic materials immediately after sealing, known as Hot Tack. This is crucial for ensuring that packaging can withstand high loads during the filling process.

Applications: The tester is used for Hot Tack Tests, Heat Seal Tests, Seal Strength Tests, and Tensile Tests.

Standards: The device complies with ASTM F1921 and ASTM F2029 standards.

Features: The tester includes digital P.I.D temperature control, microcomputer control with digital display, PVC operation panel, four force testing ranges, six testing speeds, manual and pedal starting modes, and RS232 connectivity.

Contact: Yarina Gao Email: [email protected] Phone: 086-531-85060139 LABTHINK HTT-L1 HOT TACK TESTER In the heat sealing process, contents are dropped into the bag immediately after the horizontal seal bars have opened. 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 is what we called Hot Tack. Since the content can be heavy, the hot seal must be able to withstand high loads, thus requiring a high hot tack force. This measurement will be of influence while upgrading packaging materials or packing production processes. Labthink Hot Tack tester is right used to evaluate product seal strengths by performing hot tacking testing according to ASTM F1921 (method B).
