Composite film heat seal tester 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.
