Shaping a Circular Future, material by material
ECO PEF™ is Leaf Bio’s flagship
PEF resin brand, designed to
redefine packaging with plant-
based innovation.
ECOPEF™
ECOPEF™ is more than a resin — it is Leaf Bio’s commitment to a future beyond oil.
Crafted from renewable resources, ECOPEF™ embodies the balance of performance and responsibility: exceptional barrier protection, thermal resistance, and durability, with full compatibility in today’s recycling systems.
From bottles to films, ECOPEF™ enables the world’s leading brands to create packaging that protects both products and the planet — setting a new standard for sustainable materials.
PEF
Scientific Name: Poly(ethylene 2,5-furandicarboxylate) (PEF) Molecular Formula: (C₈H₆O₅)ₙ
PEF is a high-performance polyester synthesized from FDCA and ethylene glycol, derived entirely from renewable biomass. Recognized as a promising successor to PET, PEF resin offers exceptional gas barrier performance, heat resistance, and mechanical strength — all with a significantly lower carbon footprint and energy demand. Fully recyclable and designed for circularity, PEF sets a new benchmark for sustainable plastic alternatives.
As a versatile base material, PEF resin can be transformed into multiple forms to serve diverse industries:
- Fibers: Applied in BioFleax™ textiles, offering natural antibacterial properties, moisture-wicking comfort, and inherent UV protection.
- Packaging: In food, beverage, and personal care, PEF bottle-grade resin extends shelf life, reduces material usage, and lowers transport emissions — without compromising performance.
- Films: High-barrier, biodegradable films and coatings for packaging and industrial use.
from fibers to bottles to films, PEF Resin is more than a material — it is a catalyst driving the transition toward a low-carbon, fully circular future.
Designed for Performance,
Made for Sustainability
