Unlocking the potential of bio-based adhesives in packaging by an integrative research approach

Research question

This study addresses the challenge of controlling the dewatering behavior and nanostructural organization of polymer–montmorillonite soft matter systems, which are widely used as
adhesives in packaging applications. While performance depends on the interplay between polymer
properties, filler concentration, and water dynamics, this relationship remains poorly understood,
particularly for bio-based polymers, which often suffer from poor coating quality, slow dewatering rates,
and inadequate cohesive strength, leading to unstable processing. To bridge this gap, we combine
experimental scattering techniques and molecular dynamics simulations to systematically vary polymer
chain length, stiffness, and clay content, thereby uncovering fundamental structure–property
relationships and developing a predictive, transferable framework to guide the design of advanced
polymer–clay composites with tailored dewatering and mechanical properties.

Sustainability aspect

This project supports the WISE strategy by advancing sustainable, highperformance packaging through the replacement of fossil-based adhesives in carton packages with biobased alternatives derived from non-edible waste streams. By integrating computer simulations with
experimental techniques, the research addresses the interplay between structure, processing, and
performance, aligning with WISE’s thematic areas of Circularity & Replacement, as well as Discovery. The
work directly contributes to UN Sustainable Development Goals SDG2 (Zero Hunger), SDG9 (Industry,
Innovation and Infrastructure), and SDG12 (Responsible Consumption and Production) by enabling robust,
recyclable, and renewable packaging solutions that protect food globally, reduce reliance on fossil
resources, and foster circular material flows. Through innovation and collaboration across the value chain,
the project aims to deliver next-generation adhesives that meet stringent performance requirements
without compromising sustainability.
