releaf®, developed by Avantium, is a plant-based polyester known scientifically as polyethylene furanoate (PEF). Derived entirely from renewable feedstocks, releaf® represents a next-generation sustainable packaging solution with full recyclability. This material distinguishes itself through superior barrier properties compared to conventional plastics, effectively preserving carbonation in beverages and extending the shelf life of food products. As such, releaf® is particularly suitable for use in bottles, films, and textile fibers.

In addition to its functional performance, releaf® offers a range of technical and environmental benefits. Its high mechanical strength allows for the creation of lighter and thinner packaging, thereby reducing material usage and waste. The polymer’s thermal stability and compatibility with existing recycling infrastructures further support its integration into circular systems. Lifecycle analyses indicate that PEF carries a significantly lower carbon footprint than fossil-based plastics, aligning with global efforts to reduce greenhouse gas emissions.

Avantium collaborates with several prominent companies—including Hoogesteger, Amcor, and Albert Heijn—to implement releaf® in commercial applications, bringing sustainable packaging alternatives to the European market.

Positioned as both a material and a mission, releaf® is intended to contribute to the transition away from fossil-based plastics by offering scalable, bio-based alternatives.
