The aim of the research is the creation of a packaging system for the so-called "farmers markets". The solution consists in a bag obtained from the combination of two layers: one, external, made in recycled paper and the other, internal, made in mater-bi (a compostable bio-plastic). The identity of the bag is then declined according to the four seasons: each paper layer has on its surface a different painting by G. F. Millet (one per season) and each mater-bi layer is characterized by a specific colour; the adding of a label with specific information and pictograms related to the content, is used to close each bag. In other words, the packaging system uses two different communication registries: one more emotional recalling rough and traditional materials, colours and images; the other, more informative, of the label and its graphical structure.
