Failure analysis and Improvement of Heat Sealing Testing Method
In Thailand, the major cause of heat sealing problem is that temperature at the interface surface ofmaterial is not monitored and controlled appropriately. Conventional testing method of seal strength ASTMF88-07 and JIS Z0238 are extensively used in industries and researches. Conventional method use wide temperaturepitch for heat sealing. The variation of heat seal strength of conventional method is very high becauseto temperature traceability use only display from heat sealing machine. With the innovative method,temperature of melting surface is monitored and controlled directly. In this study, the step of heating temperaturefor heat seal strength testing is 1-2℃ for obtaining details of heat seal strength. Temperature measurementand display were calibrated before applying heat sealing process. The differences from the conventionmethod and proposed method are discussed. The objectives of this research are as follows. Firstly, investigationof trouble section in conventional testing method. Secondly, the new test method for high accuracy ofheat seal sample. Experiments are conducted to prove the superiority of new proposed method.
