Manufactured as a typical paperboard-based composite structure, Combidome is shaped to a domed top, with the single-action domeTwist screwcap positioned in the centre.
The closure's inner 28mm diameter ensures "smooth pouring" with no splashing, as well as enabling consumers to drink straight from the carton pack.
Markus Boehm, SIG Combibloc chief market officer, says: "With combidome, we have created a carton pack that offers a new dimension in differentiation and convenience, and brings with it all the proven environmental benefits of the beverage carton."
The Combidome filling machine is based on existing SIG Combibloc technology, capable of running up to 12,000 carton packs/hr.
A change of packaging design can be implemented "without interrupting the production process, and with no wastage at all", the company says, only requiring an operator to switch the carton sleeves in the magazine.
Diagonally angled nozzles fill into the corners of the carton packs, in order to keep foaming of the beverage to a minimum, creating a: "Very low-oxygen filling process, which is beneficial for product quality."
To manufacture Combidome, SIG Combibloc uses only raw paperboard made of pulp from trees harvested in FSC-certified forests (Forest Stewardship Council) or other controlled, fully checked sources.
The company says Combidome and its closure, in keeping with all its carton packs, are fully recyclable, and are compatible with all national recycling and waste management systems.
Part of the New Zealand based Rank Group, SIG Combibloc achieved a turnover of €1,450 million in 2011 with around 4,870 employees in 40 countries.
