  • Temperature indicating method, temperature indicating label and method for manufacturing the label
    Patent number: 9816870
    Abstract: A temperature indicating method, a temperature indicating label used by this method, and a method for manufacturing the temperature indicating label, includes: a, determining the target temperature, adopting the thermal induced shape memory polymer material to manufacture the temperature indicating label; b, heating the temperature indicating label to make it achieve or exceed the initial temperature of glass transition or melting transition but be lower than the terminal temperature of glass transition or melting transition, then finishing the predeformation treatment; and c, placing the predeformed temperature indicating label into the environment which needs temperature indication for a while, observing whether spontaneous shape recovery happens to the label and judging whether the environment temperature has once reached or exceeded the target temperature.
