Rottneros AB, one of the world's leading suppliers of first-class market pulp, is now investing in Blue Ocean Closures and becomes a co-owner of the Swedish start-up, developing proprietary fiber-based packaging materials.

Since just two years, Blue Ocean Closures AB has developed technology to produce fiber-based closures for consumer packaging at large scale, aiming to replace current plastic solutions on a global market. The innovative technology and material have potential for many more high volume use cases and making an impact in terms of reducing plastic pollution and its climate effects.

"Blue Ocean Closures is leading the way in a very exciting new field with their vacuum press forming technology. At Rottneros we see this field as complementary to our work in wet moulding and exploring the opportunities within dry processes fits very well with our market strategy," says Lennart Eberleh, CEO, Rottneros AB.

Blue Ocean Closures is a Swedish sustainability start-up, transforming the packaging industry through the design and manufacture of fibre-based screw caps and lids.

Rottneros is an independent producer of market pulp.
