At Interpack 2026, the direction of the packaging industry became increasingly clear. Sustainable packaging is no longer driven solely by future ambitions or regulatory discussions. Across the exhibition halls, the market demonstrated that renewable materials, fibre-based packaging, and advanced biobased barrier solutions are now moving rapidly towards industrial-scale implementation.
For Innomost, Interpack 2026 confirmed a significant shift in market expectations. Interest in renewable raw materials, circular economy innovation, and high-performance biobased barrier solutions has accelerated throughout the packaging value chain. At the same time, Suberinno™ Suberin and biobased barrier solutions are attracting increasing attention as companies search for scalable alternatives to fossil-based barrier materials.
Fibre-based packaging continues to expand into demanding applications
One of the strongest themes at Interpack 2026 was the rapid evolution of paper and paperboard packaging. Fibre-based materials are increasingly being developed for applications that require improved resistance against moisture, grease, and oxygen, areas that have traditionally relied heavily on plastic and multilayer structures.
This development is closely connected to advances in barrier coating technologies. Throughout the exhibition, companies presented new material innovations designed to improve packaging performance while maintaining recyclability and reducing fossil dependency.
The range of applications was extensive. Many new packaging concepts were visible. Major international brands also showcased commercially available fibre-based packaging, underlining how sustainability targets are now directly shaping packaging development and procurement decisions.
The broader packaging ecosystem is evolving as well. New companies are entering the market both in paper production and advanced barrier materials, while chemical industry players are investing more actively in renewable coating technologies and biobased barrier solutions.
The transition towards sustainable packaging is no longer experimental. It is becoming an industrial reality.
Suberinno™ Suberin responds to growing demand for biobased barrier solutions
One of the most important observations at Interpack 2026 was the growing industry interest in naturally derived functional materials. As packaging producers and brand owners search for renewable alternatives with strong technical performance, suberin is emerging as a highly relevant material for next-generation biobased barrier solutions.
Suberin is a naturally occurring hydrophobic biopolymer found in birch bark. At Innomost, Suberinno™ Suberin is developed from upcycled birch bark side streams generated by the forest industry. This approach supports circular economy principles by transforming underutilised biomass into high value functional materials for industrial applications.
The increasing relevance of Suberinno™ Suberin is strongly linked to the packaging sector’s demand for materials that combine sustainability with functionality. The natural hydrophobic properties of suberin make it particularly interesting for moisture-resistant and grease resistant packaging applications. At the same time, its renewable origin supports efforts to reduce dependence on fossil-based materials and improve the sustainability profile of packaging structures.
At Interpack 2026, discussions surrounding Suberinno™ Suberin and biobased barrier solutions increasingly focused on industrial scalability, process compatibility, and commercial readiness. This reflects a broader industry shift from conceptual sustainability discussions towards validated material solutions that can integrate into existing converting and coating processes.
For Innomost, this market development creates significant opportunities. Suberinno™ Suberin aligns closely with the packaging industry’s growing need for renewable barrier materials, circular economy innovation and responsibly sourced raw materials. Suberinno™ Suberin is a versatile material that works both as a 100% standalone solution or in existing coating formulations. It also enables new innovations, delivering added functionalities such as oxygen barrier performance.
Industrial validation remains essential
Although the momentum around sustainable packaging and biobased barrier solutions is clearly accelerating, Interpack 2026 also highlighted an important industry reality. Commercial adoption requires more than material innovation alone.
Industrial testing, performance validation, processability, and customer case development remain critical steps in building market confidence. For biobased barrier solutions, such as Suberinno™ Suberin, successful industrial trials and strong reference cases will play a central role in accelerating broader market implementation.
At the same time, collaboration across the value chain is becoming increasingly important. Material developers, chemical companies, converters, packaging manufacturers and brand owners all have a role in supporting the transition towards scalable and commercially viable sustainable packaging solutions.
Looking ahead
Interpack 2026 demonstrated that the future of packaging will be increasingly shaped by renewable materials, fibre-based structures and advanced biobased barrier solutions.
For Innomost, the exhibition reinforced the growing global interest in suberin and the strong future potential of Suberinno™ Suberin within sustainable packaging development.
As the industry continues to search for scalable alternatives to fossil-based materials, biobased innovations , such as Suberinno™ Suberin, are becoming an increasingly important part of the conversation. The next phase will focus on industrial validation, collaboration and commercial implementation as sustainable packaging solutions move further into the mainstream global market.
