SIG adds convenience to sustainable EcoPlus pack

28 November 2012


SIG Combibloc is now offering its EcoPlus aseptic carton packs with the company’s very lightweight combiCap screw cap closure.

When they were first launched, Combibloc EcoPlus packs had no closure, but SIG has now enhanced the convenience of the carton pack format by adding the “extremely resource efficient” combiCap.

“We wanted to make sure the consumer doesn’t have to compromise,” says Combibloc EcoPlus product manager Tamara Jevremovic. “He should be able to get a carton pack that is convenient and eco-friendly, and with EcoPlus we’ve managed to do just that.”

The screw cap combiCap weighs 1.9 grams – about 60% less than the first screw cap launched by SIG Combibloc, Jevremovic adds.

The combination of the composite structure of EcoPlus, based on a specially sourced, FSC-certified wood-based raw paperboard, and the combiCap has been shown to generate 28% less CO2, when compared to a conventional 1-litre carton pack of the same format from SIG Combibloc (based on the life cycle of the carton pack from the production of the raw materials to the finished carton pack).

Consisting of a flange with integrated cutting ring and a screw cap, combiCap is based on a process developed by SIG that has already become internationally established in use with other SIG closures.

The screw cap is applied onto a hole coated over by the carton pack’s external polymer laminate layer after the product has been filled.

With a single twist of the screw cap, the tamper evidence feature on the original seal is broken with an audible click, and the pack is opened.

Europe-wide consumer tests have shown that the cap is easy to open and offers a good pouring action, SIG Combibloc says.
