Applications

The hot - tack tensile tester is an instrument specifically designed to test the hot - tacking and heat - sealing properties of packaging materials. Its main uses include, but are not limited to: - Evaluating the Heat - Sealing Performance of Packaging Materials: By simulating the heat - sealing conditions of packaging production lines, it tests the strength of materials after heat - sealing, ensuring that packaging materials can maintain their integrity during transportation and storage. - Quality Control: During the production of packaging materials, regular testing with a hot - tack tensile tester can promptly identify production issues, ensuring stable and reliable product quality. - Material R & D: In the process of developing new materials, the hot - tack tensile tester can be used to evaluate the impact of different formulations and processes on the heat - sealing performance of materials, providing a basis for material optimization. - Applications in Multiple Fields: In addition to packaging materials, the hot - tack tensile tester can also be used to test the peeling and breaking properties of soft materials such as adhesives, adhesive tapes, self - adhesive labels, and paper, providing technical support for the application of these materials.

Test Procedures

1.Device Preparation

Check the integrity of components (heat-sealing module, tensile sensor, clamps) and connect the power supply (110-240VAC, 50-60Hz).

Power on the device, activate the digital P.I.D temperature control system, and preheat to the preset temperature (wait for temperature stability).

2.Sample Preparation

Cut the packaging material (e.g., plastic film, composite packaging material) into standard-sized specimens (ensure surface is clean, free of impurities or damage).

3.Parameter Setting

Operate the 160×128 dot graphic LCD (with alphanumeric keypad) to set test parameters:

Heat-sealing pressure: 0.05–0.7MPa (adjust per material type).

Heat-sealing time: 0.1–999.9s (match production line conditions).

Hot-tack time: 0.1–999.9s (for hot-tack performance evaluation).

Force range: Select appropriate range (e.g., 0–200N) based on material stiffness.

4.Sample Installation

Fix the prepared specimen in the heat-sealing clamp (ensure alignment to avoid offset) and secure the other end in the tensile test clamp.

5.Test Execution

Start the heat-sealing process: The device completes heat-sealing under the set pressure/time/temperature.

Trigger the hot-tack tensile test: The instrument automatically applies tensile force to the freshly sealed specimen and records real-time data (e.g., hot-tack strength, heat-seal integrity).

6.Data Acquisition & Analysis

The built-in data system automatically collects test data, generates force-time curves, and calculates key indicators (e.g., heat-seal strength, hot-tack force).

7.Post-Test Operation

Remove the tested specimen, clean the clamps/heat-sealing module to avoid residue buildup.

Save the test report (including parameters, curves, and results) via the device interface.

Power off the device after cooling.

FAQ
