As an aromatic polyester from ethylene glycol it is a chemical analogue of polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). PEF has been described in (patent) literature since 1951,[2] but has gained renewed attention since the US department of energy proclaimed its building block, FDCA, as a potential bio-based replacement for purified terephthalic acid (PTA) in 2004.[3] Benefits over PETOne life-cycle assessment showed that replacing PTA in the production of PET by bio-based FDCA for the production of PEF has a potential for significant reductions in greenhouse gas (GHG) emissions and non-renewable energy use (NREU).[4] Furthermore, PEF exhibits an intrinsically higher gas barrier for oxygen,[5] carbon dioxide[6] and water vapor[7] than PET and can therefore be considered an interesting alternative for packaging applications such as bottles, films and food trays.
