An apparatus, system and method for a time temperature indicator (TTI) which is capable of providing a summary of the time and temperature history of a good to which it is coupled, optionally including with regard to providing an indication as to whether one or more temperature thresholds have been breached. According to other embodiments, the TTI specifically provides an indication as to whether a temperature threshold at or around the freeze point has been breached, optionally even without providing a time and temperature history.

This invention relates to thin indicating devices, such as time-temperature indicators and a method of making by applying and UV curing one or more layers of indicating composition are disclosed. For example, an indicator layer is applied on substrate and cured with UV light, immediately followed by an application of an activator layer which is cured by UV light. The device can have other layers, such as a permeable barrier between the activator and indicator layer and a top protective layers which are also UV cured. This fast curing method prevents premature reactions, e.g., diffusion of activator into indicator layer and vice versa during manufacturing.

A dual-function heat indicator for monitoring two or more modes of heat exposure is described. A manufacturing process for the dual-function heat indicator is also described. Dual-function heat indicators as described may be useful for monitoring the exposure of host products, with which the dual-function heat indicators may be associated, to cumulative ambient heat exposure and to a peak ambient heat exposure, and for other purposes.
