Shaping a Circular Future,
material by material
ECOPEF® is a high-performance plant-based material system created for packaging that needs to protect more than a container can show.
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 next-generation material synthesized from FDCA and ethylene glycol sourced 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
ECOPEF® offers high-performance, plant-based solutions for packaging and films. Combining superior barrier, thermal resistance, and mechanical strength, it provides a renewable, recyclable alternative to fossil-based plastics — enabling both technical excellence and environmental responsibility.
Key Advantages
6–10× higher oxygen barrier than PET, extending shelf life for beverages and foods.
Reliable for cold-chain transport and daily use.
Withstands temperature up to 85°C，ideal for hot-fill processes and pasteurization.
Made entirely from plant-based resources, compatible with existing PET recycling systems.
Typical Applications
Coffee, tea, flavored drinks, milk, yogurt drinks, beer, soda, sparkling water.
Fresh produce, baked goods, and aroma-sensitive foods.
A Vision for
Greener Materials
From bottles to films, ECOPEF unites performance with sustainability — lowering carbon emissions and driving the shift toward a circular economy.
