Blue Ocean Closures has announced its new Paper-Plug range of integrated fibre-based opening and dispensing concepts, combining an internal fibre screw closure with a direct interface to carton and corrugated board structures.
The range is designed to directly integrate into board-based packaging structures and is said to enable packaging formats that previously have often depended on glass, metal or plastic, while creating opportunities for new consumer experiences and new product architectures.
Potential application areas include dry and frozen foods and ingredients, cleaning products, refill and reuse systems and cartons and hybrid board formats. Blue Ocean Closures states that the concept also supports reduced fossil material dependency, lower carbon footprint potential and new opportunities for differentiation and branding.
The company plans to open the Paper-Plug concept for standardized solutions and proprietary collaborations, aiming to enable converters, brands and technology partners to develop differentiated packaging systems together.
Staffan Andersson, CTO at Blue Ocean Closures, says:
“Paper packaging has historically been strong in surfaces and structure but limited in functionality wherever advanced opening, dispensing and reclosure features were needed. With Paper-Plug, we want to expand what paper packaging can become. We believe this opens a completely new design space where sustainability, convenience and economics increasingly reinforce each other rather than compete.”
Earlier this year Dutch nutraceutical company Live Puri replaced the metal closures for its vitamin products with fibre-based caps from Blue Ocean Closures, aiming to reduce its CO2 footprint. The NutraCap is apparently recyclable as paper and made from renewable fibres.
In related news, PulPac revealed a new generation of ‘plastic-like’ Dry Molded Fiber caps, developed alongside PA Consulting and Optima to replace conventional plastic caps and unlock new branding opportunities. According to early testing, they perform well across parameters like thread engagement, opening and closing functionality, sealing architectures, and overall tactile experience.
