Abstract: Temperature indication labels, including low temperature ascending indication labels, that provide a visible color change when a temperature rises above a target temperature, in some applications a target temperature below room temperature. For low temperature ascending indication labels, the indicator needs activated by cooling or freezing. A transparent polymer layer is present over a deposition of a temperature indication composition in a suitable thickness to protect (insulate) the same from environmental interference, such that the temperature indication composition better reflects the temperature of the thermal mass to which it is adhered and intended to monitor. One example application a low temperature ascending indication label is a blood bag filled with blood, which is stored at 6° C. and transported at 10° C. Another is refrigerated storage of medical items and food to be stored in a range of 2° C. to 8° C.
