The goal of this thesis is to study the reliability of the LIG (Laser Induced Graphene) process applied to the realization of smart tags for the secondary agro industry packaging. The LIG process consists in the localized pyrolysis of carbon-based substrates after a direct laser treatment, which induces a photothermal reaction on the surface of the substrate. Thanks to this mechanism, carbon atoms are rearranged to form graphitic structures. In this way conductive porous graphene can be patterned on the material’s surface. Nowadays, the secondary agro industrial sector results to be a huge source of worldwide resource consumption. To optimize the resource employment and hence to avoid wastes, smart packaging solutions can be significantly useful and so be integrated in the supply chain.
