[**Blue Ocean Closures**](https://www.blueoceanclosures.com/?ref=packaging-europe.ghost.io) **(BOC) has stated that its latest generation of fibre screw caps can ‘match or outperform’ fossil plastic in material costs, while delivering significantly lower energy consumption during production.**

The company says this is a result of advancements in its 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 ‘widely available and less expensive’ than traditional fibre-forming and fossil-based plastics.

Combined with production cycles said to be under two seconds and an energy requirement roughly one-tenth that of conventional plastic moulding, this development seeks to establish fibre closures as a ‘cost leading, low-carbon’ alternative for a wide range of packaging applications.

“For the first time, we can say that fibre-based closures can be cost competitive - or even lower in cost - compared to fossil plastics, while using only a fraction of the energy,” says Lars Sandberg, CEO of Blue Ocean Closures. “This is the moment when sustainability and profitability truly align.”

Last month, Scandinavian company [Great Earth](https://www.greatearth.se/?ref=packaging-europe.ghost.io) announced it will be [implementing](https://packagingeurope.com/news/great-earth-shifts-to-paper-caps-for-all-supplement-bottles/13377.article?ref=packaging-europe.ghost.io) paper caps for all its supplement products, following a successful pilot of fibre-based closures in collaboration with Blue Ocean Closures. Referring to consumer surveys conducted on the pilot, Great Earth states that 90% of consumers found the paper cap more user friendly, 100% viewed it as more environmentally friendly and 90% prefer the paper cap and would buy it again.

In similar news, [SIG](https://www.sig.biz/en?ref=packaging-europe.ghost.io) and [PulPac](https://www.pulpac.com/?ref=packaging-europe.ghost.io) formed a [strategic partnership](https://packagingeurope.com/news/sig-and-pulpac-join-forces-for-large-scale-paper-based-closure-production/13109.article?ref=packaging-europe.ghost.io) back in July, aiming to utilize the company’s Dry Molded Fiber technology and establish a development program for large-scale production of paper-based closures for SIG’s aseptic cartons. The technology apparently delivers lower CO2 emissions compared to plastic solutions and ‘unparalleled design flexibility’.
