In FMCG, and particularly in the food sector, packaging is one of the key elements in offering a solution to the equation between sustainability and convenience. Both its evolution and its dimension (technological, social, economic, etc.) make it possible to look at the packaging sector from different perspectives, such as the eminently functional (whether or not the packaging fulfils its conservation role, for example) or the aesthetic (the packaging manages to attract attention and reflect the brand’s values). But there are other key factors to take into account in order to achieve true differentiation in the market.
