PEF as a multilayer barrier technology: a sustainable way to enable long shelf life in PET bottles

Performance of PET/PEF/PET multilayer bottles

Avantium-30-07-2020-min

Avantium Renewable Polymers, a 100% subsidiary of Avantium, plans to build a flagship plant for the production of FDCA (furandicarboxylic acid), a monomer for high performance polyesters such as PEF (polyethylene furanoate). The plant, which is aimed to be on-stream at the start of 2023, will have a nameplate capacity of 5 metric kilotons per year and be located in Delfzijl, the Netherlands.

Avantium is already producing FDCA and PEF at a smaller scale from its pilot plant in the Netherlands and is using this material to accelerate the market introduction of various high-value applications, including those in packaging. Made from renewable resources, compatible with existing recycling equipment and with outstanding barrier properties (approximately 10 times better O2 and 20 times better CO2 barriers with respect to PET /1/, PEF is full of potential promise: not as a replacement for PET, but as a side-by-side complementary technology, enabling a full polyester solution for applications where both the performance and sustainability of the incumbent is not sufficient.
