The main aim of this thesis has been the development of sustainable polymeric materials withpotential applications in food packaging and the study of the relationship between differentparameters and the transport properties. For that purpose, different systems have been analysed: a)polymer blends based on a biodegradable polymer with improved barrier properties whilemaintaining an adequate hydrolytic degradation. b) Nanocomposites that show improved barrierproperties. c) Transport properties of organic solvents on biodegradable polymers. d) Synthesis offully chemically recyclable copolymers that present outstanding barrier and mechanical propertiesthat are similar to commercial poly(ethylene terephthalate) and poly(ethylene) and better thanbiodegradable poly(lactide) and poly(hydroxybutyrate) ones. // The main aim of this thesis has been the development of sustainable polymeric materials withpotential applications in food packaging and the study of the relationship between differentparameters and the transport properties.
