HTT-01 Hot Tack Tester

Model: HTT-01
Temperature Accuracy: ±0.2 °C
Temperature Uniformity: ± 1 °C
Payment Terms: TT , LC , Others

Brief Introduction 

The hot tack strength refers to the sealing strength of the soft plastic package after the heat-sealed edge has not yet cooled. If the hot tack strength of the packaging bag is poor, the bag will be broken under the impact of the product or air leakage will occur due to damage to the heat-sealed edge. Therefore, setting appropriate heat sealing parameters and improving the hot tack strength of soft plastic packaging bags are important measures to reduce the rate of bag breakage at the production site or to reduce air leakage during storage.

HTT-01 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.

Technical Features

- Four test modes of hot tack, heat seal, peel and tensile test provide users with more combinations of test conditions

- By using digital P.I.D temperature control technology, the preset sealing temperature can be achieved in a short period without fluctuation.

- Equipped with advanced displacement control system, displacement accuracy can reach 0.1mm

- Four force ranges, advanced servo drive system, 0.05-3000mm/min stepless speed regulation, which can meet the different test needs of users
