The use of renewable biobased carbon feedstock is seriously taken into consideration these days because it offers the intrinsic value of a reduced carbon footprint and an improved life cycle analysis, within the framework of a sustainable and environmental development. Many efforts both from the academic as well as from the industrial world have been therefore devoted to the development of bio-based alternatives to fossil-based plastics, in view of a greener and more sustainable economy. Indeed, the bioplastic production is expected to increase from the actual 1.7 million tons to over 7.8 million tons in 2019, highlighting a very fast growing rate1. 2 Lacticacid(obtainedbyfermentationofrenewableagriculturalrawmaterials ),2,5-furandicarboxylic acid (obtained from the oxidation of hydroxymethylfurfural (HMF), in turn derived from the dehydration of (poly)saccharides)3 and succinic acid (obtained by sugar fermentation)2 have emerged as some of the most competitive among the different renewable starting materials. For food industry, the prediction and control of the ageing of the packed food are a major goal to reach the expectation of the consumers. Packaging contributes to this final quality of the product by appropriate berrier properties. In this framework, the design of a material plays an important role to ensure optimized final properties for an intended use. The aim of this contribution is therefore to correlate the ―ad hoc‖ desighed polymer chemical structure with final properties in order to extrapolate useful correlations.
