A Swedish company has developed a fibre-based cap for food and drink cartons.
Blue Ocean Closures said its product could be on sale early next year.
The company estimates that more than 100 billion plastic caps are used on cardboard food and drink cartons around the world each year.
It claims that its alternative lid, developed and adapted specifically for aseptically packaged products such as long-life dairy, juice and soup, is “competitive” and “recyclable”.
Chief commercial officer Ola Tönnberg said: “Our over-cap made of fibre-based material has a great fit to these products.
“Since already the carton board is recyclable as paper, so should of course the cap be too.”
She added: “If you consider the sheer volumes, the solution we are offering can make a significant impact.
“Moving forward we are eager to build relationships with potential partners, anticipating first volumes to reach the market early 2025.”
