Carlsberg beer cans are to be stuck together with glue as it becomes the first brewer to abandon plastic rings.
Reported to be “a world first for the beer industry” the design with reduce the amount of plastic used in traditional multi-packs by up to 76%, the Danish company said.
After a three year development process, Carlsberg insists the dots of glue bonding its new “snap packs” are strong enough to withstand journeys from shelves to homes, yet sufficiently brittle to break when twisted.
Head of sustainability at Carlsberg, Simon Boas Hoffmeyer said once the snap packs are rolled out worldwide the company will reduce its plastic use by 1200 tonnes a year – the equivalent of 60 million plastic bags.
Other sustainable packaging solutions announced by Carlsberg include a switch to ‘cradle-to-cradle certified’ silver inks on its bottle labels to improve recyclability, a coating on refillable glass bottles to extend their lifespan and caps which remove oxygen to make the beer “taste fresher for longer”.
