Description
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.
Features
-
Five groups sealing temperature can be measured with one test
