Abstract: The present invention relates to a thermosensitive label for monitoring the quality state of a thermosensitive article. The present invention also relates to a preparation method of the thermosensitive label and a thermosensitive article using the thermosensitive label. The thermosensitive label according to the present invention comprises two laminated layers which are physically-separated of a thermosensitive function layer and an adsorption-indication function layer. The two laminated layers are stored and transported separately, and combined together in use.
Abstract: 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.
