08 Jan 2024 --- Rottneros, a global supplier of market pulp, has invested in Blue Ocean Closures and become a co-owner of the Swedish start-up, which develops proprietary fiber-based screw caps and other packaging materials. Lars Sandberg, CEO of Blue Ocean Closures, tells Packaging Insights that the investment from Rottneros is an important part of the company’s go-to-market strategy “both for advanced packaging concepts such as closures and for material sales to converters for more standard fiber products.” Sandberg says that Blue Ocean Closures sees a continued focus on reducing plastics and carbon footprint while maintaining or improving recyclability. “A relevant cost structure and high functionality will be basic demands, and we see opportunities in high volume products such as closures for beverages cartons, branded products and standard off the shelf products.”
