PEF is a 100% recoverable bio-based polymer made from renewable raw materials from plants.PEF, described as the next-generation polyester, has great potential to replace PET, a durable polymer derived from conventional synthetic resources. Compared with PET, PEF has many advantages. Not only does it reduce the overall carbon footprint of various products, but it also improves the sustainability of packaging. PEF has a higher gas barrier to oxygen, carbon dioxide, and water vapor than PET and can therefore be seen as an interesting alternative to existing packaging applications such as bottles, films, and food trays.
