This SCGC-FIRST project addresses the global challenge of plastic waste by developing high-performance, sustainable packaging materials with dramatically improved barrier properties. While recyclable and biodegradable alternatives are increasingly available, they often fail to provide sufficient protection against moisture and oxygen for food packaging applications.
In collaboration with SCG, the team will use spatial atomic layer deposition (SALD) to rapidly “print” dense oxide thin films onto sustainable mono-material packaging. These ultra-thin coatings can deliver exceptionally low water vapour and oxygen transmission rates, meeting and exceeding the stringent requirements for food preservation. The project will further develop advanced nanolaminate structures and tailored dopants to minimise moisture pathways and enhance durability.
The technology is readily translatable through NanoPrint Innovations Ltd, a startup commercialising roll-to-roll compatible SALD systems, enabling scalable manufacturing. By combining sustainability with high barrier performance, the project has the potential to transform the trillion-dollar flexible packaging industry while supporting circular economy goals.
