The temperatures on the surfaces of heat-sealed areas in liquid packaging bags made of laminated plastic films were measured to investigate temperatures and rates of fluid filling into the bags suitable for the heat sealing. Thermal images were taken immediately after heat sealing using an infrared thermography technique at heat-sealing temperatures in the range of 100 and 190℃ at rates of film feed in the range of 10 and 25m/min in a automatic packing machine. After the tests, the relationship between the distributions of temperatures obtained from the images and adhesive property between the components consisting laminated plastic films in heat-sealed areas was investigated. The results showed that the distributions of temperatures on the surfaces of heat-sealed areas can be used to evaluate the adhesive property.
