Smurfit Westrock has introduced ActiBlu, a prototype water-activated solution designed to remove the need for traditional gluelines in paper-based packaging.
The solution uses an adhesive applied during production, eliminating glue application at box closure. It is activated with a fine mist of water and seals immediately. According to the company, ActiBlu uses up to 60 per cent less adhesive than traditional hot-melt glueing and supports recyclability, helping brands meet regulatory requirements including PPWR.
Arco Berkenbosch, chief innovation officer at Smurfit Westrock, said, “ActiBlu simplifies the packing process for our customers. The transition to the solution requires a modification from glue application to spraying a fine mist of water on packing lines, reducing operational complexity while maintaining performance.”
ActiBlu is in the pilot phase, with the company working with partners to test and refine the solution in operational environments based on customer feedback.
The prototype was presented at Smurfit Westrock’s 2026 Innovation Event in the Netherlands, which brought together more than 450 customers, partners and innovation leaders from multiple industries. The event explored the role of Artificial Intelligence, sustainability and design in shaping the future of paper-based packaging, according to the company.
At the event, Smurfit Westrock also introduced three AI-based tools designed to improve packaging performance on shelf and across the supply chain, built on insights from what it said were millions of real-world market data points.
Berkenbosch added, “This is about building a future that balances innovation with responsibility: powered by people, guided by nature, and enhanced by AI. By bringing human creativity, nature’s intelligence, and advanced technology together, we’re creating solutions that are not only smarter, but more sustainable and meaningful for a changing world.”
