Innomost launches birch-bark suberin coating for fibre packaging barriers
Finnish company Innomost has developed Suberinno Suberin, a barrier material derived from birch bark suberin, aimed at replacing fossil-based coatings in fibre-based packaging. The material targets moisture, grease and oxygen barrier properties for food and non-food paper and board packs. Innomost currently produces the material at its Kokkola, Finland facility and plans to build an industrial-scale plant within two to three years.
Why this mattersA commercially scalable bio-based multi-barrier coating could let paper and board packaging displace plastic laminates while meeting PPWR recyclability requirements.
- Innomost sources birch bark from an existing side stream of the Nordic forest industry.
- The product is marketed as Suberinno Suberin.
- It can provide moisture, grease and oxygen barrier properties in a single material.
- Production currently takes place at Innomost's facility in Kokkola, Finland.
- Innomost plans to build an industrial plant and scale production within two to three years.
- University of Oulu is separately developing suberin coatings with UPM and Metsä Board.
