Product Description
Product Introduction
The Dual 5-Point Heat Seal Gradient Tester (also known as heat seal gradient tester) adopts thermal compression sealing principle. It is used to measure heat seal pressure, heat seal temperature, heat seal time and other key parameters of flexible packaging composite films, plastic film substrates, coated paper and other heat-sealable composite films. It is an essential testing instrument for laboratories, scientific research and on-site production lines.

Product Introduction
2. Application Fields
Basic Application – Film Materials
Suitable for heat seal tests of various plastic films, plastic composite films, paper-plastic composite films, co-extruded films, aluminized films, aluminum foils and aluminum foil composite films. The sealing surface is flat and smooth, and the sealing width can be customized according to customer requirements.
3. Test Principle
Heat seal materials with different melting points, thermal stability, fluidity and thickness have distinct heat sealing performance with greatly different optimal sealing process parameters.
This tester adopts thermal compression sealing method: place test specimens between upper and lower heating jaws and complete sealing under preset temperature, pressure and dwell time. By carrying out sealing tests under various temperature, pressure and time combinations, accurate heat sealing performance indicators can be obtained with supporting testing equipment.
4. Product Features
- Equipped with five groups of heating jaws and independent PID temperature control units, adopting dual-cylinder structure
- Wide jaw design allows one single jaw to prepare two 15 mm wide specimens
- Six built-in PID temperature control units with neat and tidy appearance
- Two test operation modes: manual and foot pedal; user-friendly human-machine interface with humanized anti-scald safety design
- Brand-name pneumatic components and PID temperature controllers to ensure accurate test conditions
- Special heating tubes for fast temperature rise and long service life
- Heat dissipation fans arranged on both sides with large air volume for uniform and rapid heat dissipation
