Hot Tack and Seal Strength Tester

Product catalog summary

Overview
The HTT-L1 Hot Tack and Heat Seal Strength Tester by Labthink is designed to measure the strength of heat seals formed between thermoplastic surfaces of flexible webs immediately after sealing and before cooling. This is crucial for vertical form-fill-seal packaging applications.

Applications
The tester is suitable for evaluating hot tack and heat seal performance in plastic films, laminated films, and other packaging materials. It can also perform peel, shear, tension, and other tests on adhesives, adhesive tapes, and flexible materials.

Professional Technology Features

Four testing functions: hot tack, heat seal, 180° peeling, and tensile resistance.
Digital P.I.D. temperature control system.
Four force testing ranges and six testing speeds to accommodate various customer needs.
Safety features include automatic zeroing, error alerts, overload protection, and stroke protection.
Operable manually or via pedal switch, with RS232 connectivity.
Controlled by a micro-computer with an LCD display, PVC operation panel, and menu interface.

This heat seal property is important since this situation occurs on vertical form-fill-seal packaging. Labthink HTT-L1 Hot Tack Tester is applicable in hot tack and heat seal performance tests for plastic film, laminated film and other packaging film. Meanwhile, it is applicable in peel, shear, tension and other test items for adhesive, adhesive tape, laminated film, plastic film, paper and other flexible materials. Professional Technology 4 testing functions including hot tack, heat seal, 180°peeling and tensile resistance are available in this instrument Digital P.I.D. temperature control system 4 force testing ranges and 6 testing speeds are available to meet the requirements of distinct customers Automatic zeroing, error alert, overload protection and stoke protection guarantee the safety operation Could be started manually or by pedal switch RS232 Controlled by a micro-computer with LCD display, PVC operation panel and menu interface
