Linear glycols were combined with FDCA isomers from the Henkel\u2010type reaction to synthesize three fully biobased random copolymers: 2,5\u20102,4\u2010PTF, 2,5\u20102,4\u2010PBF, 2,5\u20102,4\u2010PHF. These copolymers were compression molded and subjected to NMR, viscometry, WAXS, DSC, and TGA analyses. Evidence suggested the formation of a partially ordered phase in 2,5\u20102,4\u2010PHF. Mechanical and gas barrier properties of the synthesized copolymers were remarkably superior to the ones of both the reference homopolymers, with increased toughness, elongation at break and resistance to humidity. Interestingly, humidity improved the gas barrier performance of 2,5\u20102,4\u2010PBF, making it impermeable to CO\n                    <jats:sub>2<\/jats:sub>\n                    . These findings highlighted the potential of these furan\u2010based copolyesters for the production of mono\u2010material, potentially recyclable, and sustainable food packaging. These achievements represented promising proof of concept for an integrated biorefinery and polymerization process, designed to: 1) Completely avoid the use of solvents; 2) Start from second\u2010generation biomass; 3) Have high carbon efficiency and few purification steps.\n
