By applying a layer of etchant onto a metallized/opaque plastic film printed with one message on the top and another at the bottom, a new line of self-reading indicators facilitate packages that monitor shelf life, sterilization, and toxic agents. Nano-Indis from JP Labs can for instance, read "FRESH" when perishables are fresh and "NOT FRESH" only when their shelf-life expires; likewise they display "STERILIZED" only when medical supplies are sterilized.
