Features & Benefits
- Labeling Claims
- Materials Features
- Superior Barrier Properties
- PEF’s oxygen barrier is 10 times better than PET
- PEF’s CO2 barrier is 6 to 10 times better than PET
- PEF’s water barrier is twice as good as PET’s
- Features
Renewable: PEF is plant-based instead of fossil-based and has a 50-70% lower carbon footprint (source: Copernicus Institute at the University of Utrecht (Eerhart et al. 2012)
Reduce: PEF is superior allowing light weighting by more than 20% in line with European legislation
Reuse: PEF in combination with PET allows PET bottles to be reused by up to 5x more
Recycle: PEF has a proven fit with existing sorting and recycling facilities and can substitute small and multi-layer packaging that cannot be recycled
Degradable:
When PEF unintentionally ends up in nature, tests show that:
- Degradation tests show that PEF degrades much faster than PET under industrial composting conditions (250-400 days with air / oxygen @ 58°C in soil) (source: Accelerated study by OWS, Gent, Belgium (2019)
- Initial results from ongoing 10-year degradability field trial demonstrate that PEF degrades under ambient conditions (trial by Avantium and University of Amsterdam)
Applications & Uses
- Applications
- Plastics & Elastomers End Uses
- High-Value Applications
Multilayer bottles :- PEF as barrier layer providing performance and enabling recycling.
Single layer bottles :- Single layer PEF in small bottles for soft drinks, beer and juice, replacing glass bottles, aluminum cans and multilayer bottles, enabling closed-loop recycling.
Film :- PEF film in recyclable flexible packaging or as film used in electronics applications (e.g. displays).
Technical Details & Test Data
- More Attractive Thermal Properties
- The Tg (glass transition temperature) of PEF is 86°C compared to the Tg of PET of 74°C
- The Tm (melting point) of PEF is 235°C compared to the Tm of PET of 265°C
