Conductive inks are normally composed of conductive metal fillers and polymeric resin where the former provide mainly electrical and thermal properties, whereas the latter provide mechanical strength and mechanical interconnections with the substrate, respectively.

It is invisible to consumers, creates zero electronic waste, and is food grade safe. These specific characteristics make conductive ink an ideal choice for smart retail packaging that needs to be reasonably priced, fairly simple to implement, environmentally friendly, and made of safe materials.
