2.Why do you need a heat seal tester?<\/strong><\/h2>\n

To make a heat seal, the film must be melted together then allowed to cool down enough to become crystalline or solid. The three interdependent elements to\u00a0heat-sealing<\/strong>\u00a0are: Heat, Pressure and Dwell time, or we call sealing temperature, sealing pressure, and sealing time.<\/p>\n

The optimum combinations of three factors will highly affect efficiency of sealing machine and heat seal strength.<\/p>\n

4.Test\u00a0Principle of Laboratory Heat Seal Tester<\/strong><\/h2>\n

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.<\/p>\n

 <\/p>\n

5.Application:\u00a0<\/strong><\/h2>\n

Laboratory Heat Seal Tester<\/strong>\u00a0can be used for plastic films, composite plastic films, paper-plastic composites, coextruded films, films with aluminum coatings, aluminum foils, composite films with aluminum foil, and various other types.<\/p>\n
