Gradient Heat Seal Tester
Gradient Heat Seal Tester is for the determination of the heatsealability of a surface, or sealant layer of films, laminates, composites and polymers etc. How well the material heatseals is expressed quantitatively as seal strength as a function of the sealing conditions of temperature, time and pressure. It conforms to standards of ASTM F2029, QB/T 2358 and YBB 00122003.
Gradient Heat Seal Tester Features
1. Five groups sealing temperature can be measured with one test
2. Proximity and pressure sensor for precise dwell time andsealing pressure control
3. P.I.D. for precise sealing temperature control
4. Uniform heating by aluminum encapsulated sealing jaws and noinhomogeneous heating
5. Independent heating of upper and lower sealing jaws
6. Sealing jaw customization available in term of dimension, shape and surface
