Heat seal tester

Heat seal tester helps to evaluate the heat seal ability of a surface, sealant layer of films, laminates, composites, polymers, etc.The heat seal ability is expressed quantitatively as seal strength as a function of the sealing conditions of temperature, time and pressure.

PRINCIPLE

Place a sample between two parallel heated sealing jaws 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.
The heatsealability can be further analyzed by seal continuity, typically measured by air-leak, dye penetration, visual
examination, microorganism penetration or other technique.
