SIG Combibloc presents the bottle made of cardboard

With combidome, SIG Combibloc now presents the bottle made of cardboard. An innovation in packaging, combidome combines the best features of a carton pack with the best features of a bottle. combidome looks like a bottle, and thanks to its shape, stability and smooth pouring action, it is also just as easy to handle. And in addition, combidome offers all the proven and unrivalled benefits of a carton pack in terms of product protection, environmental and economic considerations. The entire carton pack – from the base to the dome that gives it its distinctive bottle shape and its name – is manufactured from a paperboard composite.

Markus Boehm, Chief Market Officer (CMO) at SIG Combibloc: “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 slim, sturdy combidome carton sits very comfortably in the hand. The carton pack consists of two sections: a carton body, which is composed from the base to the dome of paperboard composite, and the screw cap domeTwist. Inside the combidome filling machine, the two components are assembled into the finished carton pack, aseptically filled and securely sealed. The handy single-action domeTwist screw cap is positioned in the centre of the package’s top, and is easy to open. At 28 mm, the inner diameter of the closure is particularly large, ensuring smooth pouring and enabling consumers to drink conveniently straight from the carton pack. In an initial stage, combidome is designed as a packaging solution for non-carbonated soft drinks. The protective composite structure of the combidome carton is composed primarily of raw paperboard and polymers.

At around 75 per cent, paperboard is the main ingredient of this composite structure, and gives the carton stability. The inner polymer layers form a liquid barrier for the beverage; the outer layer keeps moisture out. Added to this is a thin aluminium layer, which protects the product from light, oxygen and external odours. This means nutrients and vitamins in the aseptically filled beverages are retained for a long time, with absolutely no preservatives – and as long as the carton pack is left unopened, there is no need for refrigeration either. 

With their high content of unprocessed paperboard, manufactured from wood, a renewable raw material, carton packs have been proven to be among the most environmentallyfriendly packaging solutions available for long-life beverages. The same applies for combidome carton packs. This has been demonstrated in an independently verified, ISOcompliant life-cycle assessment conducted in 2012. For instance, considered over the entire life of the packaging, combidome carton packs generate 41 per cent less CO2, use 51 per cent fewer fossil resources, and consume 33 per cent less primary energy than disposable PET multilayer bottles; when compared to disposable PET monolayer bottles, these figures are 27 per cent for CO2, 42 per cent for fossil resources and 20 per cent for primary energy. Compared to disposable glass bottles, combidome generates 75 per cent less CO2, uses 66 per cent fewer fossil resources, and consumes 60 per cent less primary energy.

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 sources which are checked against legality and also consider other key social and environmental aspects. This means SIG Combibloc is also able to offer combidome carton packs with the FSC label. The label makes it easier for environmentally-conscious consumers to make the right purchasing decision at the sales shelf. The label provides a verification that appropriate quantities of wood originating from FSC-certified, well-managed forests were used to manufacture the raw paperboard. Just like all other carton packs from SIG Combibloc, combidome and its closure are fully recyclable, and are compatible with all national recycling and waste management systems. combidome can be disposed of and recycled as a single unit.
