Abstract: The present invention relates to a time-temperature indicating module that causes a spread material whose degree of diffusion changes with temperature change to be absorbed and diffused into a diffusion material through induction of a crack, guides a diffusion direction of the spread material through a guide line printed in a longitudinal direction of the diffusion material and also enables a clear start time point of diffusion to be displayed.
Abstract: The present invention relates to the time-temperature indicating module which allows the user to trigger the bursting of the starting member with a simple motion and generate a crack so that the spread material interposed inside spreads via the crack. The present invention also relates to the manufacturing method of the time-temperature indicating module that strengthens a sealed section of the time-temperature indicating module using laminating by heat sealing to prevent the spread material from leaking or flowing out.
