Fibre screw caps on a trajectory towards equal or lower in cost than fossil plastic
Blue Ocean Closures (BOC), the Swedish pioneer in fibre-based packaging innovation, recently announced a major milestone: its latest generation of fibre screw caps can match or outperform fossil plastic in material cost, while delivering significantly lower energy consumption during production.
This marks a crucial step toward making sustainable materials not only the preferred environmental choice, but also the most cost-efficient commercial option for global packaging producers.
Blue Ocean Closures (BOC), the Swedish pioneer in fibre-based packaging innovation, today announces a major milestone: its latest generation of fibre screw caps can match or outperform fossil plastic in material cost, while delivering significantly lower energy consumption during production. This marks a crucial step toward making sustainable materials not only the preferred environmental choice, but also the most cost-efficient commercial option for global packaging producers.
The breakthrough results from continuous advancements in BOC’s proprietary forming technology, which enables the forming of renewable fibres directly from virgin or recycled carton board feedstock – a material and technology combination that is both widely available and less expensive than traditional fibre-forming and fossil-based plastics. Combined with production cycles below two seconds and an energy requirement roughly one-tenth that of conventional plastic moulding, this development establishes fibre closures as a truly cost-leading, low-carbon alternative for a wide range of packaging applications.
Blue Ocean Closures’ new cost position follows several years of intensive R&D and industrial collaboration with early adopters and leading global brands in a pioneering community including Great Earth and The Absolut Group. The company’s technology enables high-speed production of recyclable fibre components that integrate seamlessly into existing paper recycling systems, meeting the accelerating demand for circular packaging solutions driven by global brand commitments and new EU regulations.
Beyond sustainability and cost efficiency, BOC’s fibre closures also open new creative opportunities for brands. Their natural look, tactile feel and customizable geometry provide high shelf impact and strong consumer preference, helping brands differentiate through both design and sustainability. This combination of technical performance, low-cost substrate and consumer appeal establishes a new value dimension for packaging innovation. AT
