The Norwegian company said the new Eco carton provides cost savings of 2-5 per cent and a carbon dioxide saving of 10 per cent compared to standard cartons. These are achieved thanks to reductions in board and cap weight.
Design aspects
In addition to the environmental aspects, Elopak considered the ergonomics of the new carton and designed it with score lines on the side and the front that improve handling and pouring.
Eco project leader Martin Wieser said: “The grip leads to a squeezing of the carton giving a more secure feeling in the hand. Easier handling creates more convenience and better pouring.”
To activate the score lines on the Eco carton, manufacturers must invest in the Eco Activator E-S Eco82 that is placed on the conveyor downstream from the filling machine. According to Weiser, this can be installed on existing Elopak lines at no significant extra cost and takes up less than one metre squared in space.
He told FoodProductionDaily.com that one of the great advantages of the new Eco carton is that this is the only investment required. There is no need to invest in new filling equipment.
“In the highly price sensitive and cost pressurised dairy markets, here is an innovation which requires minimum investment and provides a cost saving,” said Weiser.
Features and options
Eco is available in standard cross section 70x70, 1000ml, B style cartons and comes only with a screw cap. It is linked with the Elo-Cap UE light which at 2.07g is the lightest cap in the Elopak range although it is possible to use other closures in the Elo-Cap U family.
Launched first for the fresh and extended shelf life milk markets, Weiser said the Eco carton is under continuous development to further improve its green credentials and roll it out for other products such as juices.
