Abstract

A temperature-sensitive label is described. The temperature-sensitive label has a container provided with means for the application on an item to be monitored and housing a temperature-sensitive system made up of a filiform shape memory member. The filiform shape memory member is restrained to a filiform bias member provided with an engaging seat, and is introduced in such a way that in case of exposure to a temperature lower than a preset critical threshold temperature (Tc), the filiform shape memory member performs a phase transition, causing an irreversible disengagement condition visible through a transparent window.
