releaf®
Quick Overview
releaf® is Avantium's brand name for PEF (polyethylene furanoate) — a 100% plant-based, recyclable polyester made from FDCA (furandicarboxylic acid) produced via Avantium's YXY® Technology. It offers superior barrier properties vs. PET and is a drop-in replacement for fossil-based polyester.
Overview
releaf® is the commercial brand for PEF (polyethylene furanoate) developed by Avantium N.V. — a 100% plant-based, recyclable polyester that serves as a high-performance, sustainable alternative to conventional PET (polyethylene terephthalate).
PEF is produced from FDCA (2,5-furandicarboxylic acid), which Avantium manufactures from plant-based sugars (fructose) using its proprietary YXY® Technology.
Chemical Structure & Properties
Comparison: PEF (releaf®) vs. PET
| Property | PEF (releaf®) | PET | Advantage |
|---|---|---|---|
| Oxygen barrier | ~10× better | Baseline | Extended shelf life |
| CO₂ barrier | ~2× better | Baseline | Carbonated beverages |
| Water vapor barrier | Comparable | Baseline | Equal moisture protection |
| Mechanical strength | Higher tensile | Baseline | Lightweighting potential |
| Thermal stability | Higher Tg (~86°C) | ~78°C | Better heat resistance |
| Glass transition (Tg) | ~86°C | ~78°C | Higher use temperature |
| Melting point (Tm) | ~215°C | ~250°C | Lower processing energy |
Molecular Structure
- PET: Terephthalic acid (benzene ring) + ethylene glycol
- PEF: Furandicarboxylic acid (furan ring) + ethylene glycol
- Key difference: Furan ring (bio-based, 5-membered) vs. benzene ring (fossil, 6-membered)
Sustainability Profile
Bio-based Content
- 100% plant-based when using bio-based MEG (monoethylene glycol)
- FDCA from renewable fructose (starch crops, agricultural residues)
- Future: 2nd-gen feedstocks (lignocellulosic sugars, waste)
Carbon Footprint
- ~50–70% lower GHG vs. fossil PET (cradle-to-gate)
- Biogenic carbon — CO₂ absorbed during plant growth
- LCA validated by independent third parties
End-of-Life
- Fully recyclable in existing PET recycling streams (mechanical)
- RecyClass approved — PEF/PET blends recyclable in PET stream
- Not biodegradable — designed for circular recycling, not composting
- No antimony catalyst — cleaner recycling output
Applications
Primary Markets
- Beverage bottles — CSD, water, juice (superior CO₂/O₂ barrier)
- Food packaging — Films, trays, containers (extended shelf life)
- Personal care — Cosmetics, detergent bottles
- Textiles — PEF fibers, blended with cotton/TENCEL™
- Electronics — Barrier films for displays, flexible electronics
Lightweighting Potential
Due to superior mechanical properties, PEF enables thinner walls and less material use.
