Avantium and Logoplaste Sign Capacity Reservation Agreement for Releaf® to Accelerate High-Performance Packaging Innovation

AMSTERDAM, 11 November 2025, 07:00 hrs CET – Avantium N.V., a leader in renewable and circular polymer materials, is pleased to announce the signing of a capacity reservation agreement for its plant-based, recyclable polymer PEF (polyethylene furanoate), branded as releaf®, with Logoplaste Consultores Técnicos, SA. ("Logoplaste"), a global packaging manufacturer. Logoplaste and Avantium are collaborating as strategic partners within the Bottle Collective, a consortium dedicated to developing recyclable fiber-based bottles. This agreement further strengthens their partnership and supports the joint development of nextgeneration packaging solutions, extending beyond the paper bottle and into Logoplaste's core business of high-performance bottles for beverages, food, pharma, home care, and personal care.

Logoplaste is recognized for its expertise in injection molding and blow molding, delivering innovative, high-performance packaging across a wide range of applications. The company's focus on advanced barrier properties and sustainability aligns with Avantium's pioneering work in releaf®, a plant-based polymer designed for circular, high-performance packaging. As strategic partners within the Bottle Collective - a consortium that includes leading brand owners such as Diageo, Opella (formerly Sanofi), and Haleon - Logoplaste and Avantium have already contributed to advancements in recyclable fiber-based packaging. This new agreement is designed to accelerate Logoplaste's innovation pipeline, enabling the development of next-generation packaging solutions that reach beyond the Bottle Collective fiber bottles.

Under the now signed capacity reservation agreement, Logoplaste reserves future volumes of releaf® from licensed plants utilizing Avantium's proprietary YXY® Technology for releaf® production. This reservation supports Logoplaste's innovation pipeline for releaf®-enabled packaging and anticipates increasing demand for releaf® material upon successful completion of product validation. Paulo Correia, Chief Technology Officer at Logoplaste, said: "This agreement is a testament to our shared commitment to driving innovation in sustainable packaging. By securing future volumes of Avantium's releaf®, we are able to accelerate the development of advanced packaging solutions with outstanding barrier properties, supporting our customers' ambitions for circularity and performance across a wide range of applications."

Bineke Posthumus, Director Business Development at Avantium, commented: "We are excited to deepen our collaboration with Logoplaste as a strategic partner. The capacity reservation agreement reflects the growing momentum behind releaf® as a key material for next-generation, high-performance packaging. Together, we are paving the way for scalable solutions that combine renewable materials with outstanding functionality."
