Heat Seal Tester

Heat Seal Tester is professionally designed for the precise measurement of sealing temperature, time and pressure.
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.

Place a sample between two-heated sealing jaws of Heat Seal Tester with flat surfaces when the required temperature reaches equilibrium.
The upper seal jaw, driven by a gas cylinder, is pushed down, to exert a certain pressure on the sample and remain for some time. When the preset sealing time ends, the upper sealing jaw returns to its original position and the whole heatsealability testing process finishes.
