Abstract
A dual heat-freeze indicator and methods for making the same are disclosed. The dual heat-freeze exposure indicator includes a substrate, a low temperature indicator material provided in a first initial color state, a high temperature indicator material provided in a second initial color state, both supported by the substrate. The low temperature indicator material is configured to change from the first initial color state to a first exposed color state responsive to the indicator being exposed to a temperature below a low temperature threshold. The high temperature indicator material is configured to irreversibly change from the second initial color state to a second exposed color state responsive to the indicator being exposed to a temperature above a high temperature threshold. The low temperature indicator material returns from the exposed color state to the initial color state responsive to being exposed to a temperature above a reset temperature threshold.
