Heat Seal Parameters Determination
Heat Seal Parameters Determination i-Thermotek 2400 can be used for hot tack test of plastic films, composite films and other packaging materials as well it can be used to measure the heat seal strength of the test specimen after heating and sealing procedures.
Principle
Heat Seal Test: The compressed air is introduced into the gas cylinder with certain pressure. The embedded system can control the switching of the solenoid valve. The direction of the pressure applied will be changed so that the sealing jaws can move upward and downward. The packaging materials can be sealed at certain sealing pressure and sealing temperature within the dwell time.
Hot Tack Test: Clamp the two ends of the specimen in left sample grips and right sample grips (with load cell) respectively. Then pull the specimen to the hot tack test area. After the hot tack test, the driving mechanism will pull the left and right sample grips in opposite directions and the load cell can detect the electric signal and then the hot tack strength, peel strength and tensile strength can be analyzed or calculated.
Heat Seal Strength: Clamp one end of the specimen in right sample grips and the other end in the clamping seat. The driving mechanism will pull the right sample grips so that it will move in the opposite direction of the clamping seat. The load cell can detect the electric signal and then the heat seal strength can be calculated.
