TIME-TEMPERATURE INDICATOR AND MONITORING METHOD FOR MONITORING QUALITY STATE OF THERMALLY SENSITIVE ARTICLE

摘要

The present invention relates to a time-temperature indicator for monitoring the quality state of a thermally sensitive article and a monitoring method. The present invention also relates to a preparation method of the time-temperature indicator and a thermally sensitive article using the time-temperature indicator. The time-temperature indicator according to the present invention comprises two laminated layers which are physically separated, i.e. a function indication layer and an adsorption function layer. The two laminated layers are stored and transported separately, and combined together in use. Therefore, the time-temperature indicator of the present invention can be stored and transported at room temperature, which reduces the usage costs of the time-temperature indicator.
