PEF is an environmentally friendly polyester material that can be 100% sourced from bio-based materials. With a molecular structure more tightly arranged than that of PET, PEF has a superior gas-barrier property that makes it well-suited for food packaging. According to a 2023 report on the life cycle assessment of PEF released by the bioplastics company, Avantium, PEF reduces carbon footprints by more than 33% compared with PET.

Aggressive efforts have been devoted to the innovative application of PEF in anticipation of its competitive positioning as a low-carbon and eco-friendly material. FENC delved into the development of 100% bio-based PEF fiber by leveraging its R&D advantage in textile and polyester. Through multiple experiments, the Company successfully created the PEF fiber, which has been tested as being able to deliver a deep-dyeing effect under temperature settings lower than those required for polyester fibers. Delivering color strength that could reach up to 1.4 times that of polyester, PEF also reduces energy and dye consumption during production.

By applying PEF in the textile industry, FENC has expanded the market scale for bio-based products, which also accelerates its pace towards carbon reduction and sustainability.
