Introduction
The GHS-01 Gradient Heat Seal Tester is an advanced solution designed to evaluate the heat-sealing properties of various materials, including films, laminates, and packaging components. Engineered for precision, this heat seal tester is essential for ensuring the integrity and quality of packaging materials used across diverse industries such as food, pharmaceuticals, electronics, and more.
Application
Our heat seal tester is meticulously crafted to simulate the conditions under which heat seals are formed during the packaging process. By applying controlled heat and pressure to test samples, manufacturers can determine the optimal sealing parameters to achieve strong and consistent seals. This process is crucial for maintaining the effectiveness and safety of packaged products. Whether you are dealing with flexible barrier materials or heat-sealable PET films, this heat seal tester provides reliable and accurate results.
Key Features
Five Point Gradient Capability: The GHS-01 Gradient Heat Seal Tester excels with its ability to create a controlled temperature gradient across the sealing area. This feature allows for simultaneous testing at multiple temperature settings, enhancing testing efficiency and reducing the time required for seal formation assessments.
Advanced Temperature Control: The tester is equipped with a first-class P.I.D. (proportional integral derivative) temperature controller, ensuring precise and consistent temperature control. Both upper and lower jaws are made of high-quality aluminum and feature independent heating mechanisms to minimize heat loss and ensure temperature smoothness.
Accurate Pressure and Timing: The combination of an accurate timer and proximity sensor allows for precise synchronization of seal start time with jaw movement. The uniform sealing pressure is achieved through a three-way guided sealing bar, which guarantees consistent and reliable sealing results.
User-Friendly Design: Safety and convenience are prioritized with features such as an anti-scald front cover, manual and foot switches. Customization options for seal jaw dimensions, shapes, and sealing surface patterns are also available to meet specific testing needs.
Customizable Temperature Gradients: Additional gradient temperatures for both upper and lower heating can be tailored to fit particular requirements, making this heat seal tester adaptable to various testing scenarios.

Test Process
To conduct a test, place the sample between two parallel heated sealing jaws with flat surfaces. Once the desired temperature is reached and equilibrated, the upper seal jaw, driven by a gas cylinder, applies pressure to the sample for the preset duration. After the sealing time elapses, the upper jaw returns to its original position, completing the heat sealability testing process.
Heat Sealing Evaluation
Post-test, the heat sealability can be evaluated through various methods such as air-leak tests, dye penetration, visual inspection, and microorganism penetration. These assessments help in determining the continuity and effectiveness of the heat seal.
Conclusion
The GHS-01 Gradient Heat Seal Tester is a crucial tool for professionals seeking reliable and accurate measurements of heat-sealing properties. Its advanced features and customizable options make it an ideal choice for various industries requiring high precision in packaging tests.
