Lightweights can be pretty impressive as well: an ultralight PET bottle from Krones was a winner in the “Beverages” category at this year’s iF packaging design award. In recognition of this achievement, the “PET lite 9.9 carbonated” can now proudly wear the internationally prestigious iF Label.
The innovative bottle is suitable for being filled with carbonated beverages, and has a capacity of 500 millilitres. It tips the scales at a mere 9.9 grams – making it 30 to 45 per cent lighter than comparable PET containers at present on the market.
The lightweight bottle has been developed by a design team at Krones that’s already won several awards for its innovative packaging solutions. One of the designers’ paramount priorities is to develop containers that are both supremely marketable and at the same time eco-friendly. Like the PET lite 9.9 carbonated, which marries affordability to ecological interests. Since it can be produced with minimal expenditure of energy and material, it’s a true lightweight, not least in terms of production costs and minimised environmental impact.
This is achieved, for example, by dividing up the bottle into several functional areas with different wall thicknesses. Most of the PET material is located in the upper part of the bottle, where the bottle is held and opened. The walls in the lower section, by contrast, receive only half as much material. Nonetheless, the bottle is reassuring stable for handling and consumers’ use, thanks to its sophisticatedly ingenious container geometry, in which the designers have left not a single square millimetre to chance. Further significant weight savings are achieved with the special neck finish, since in contrast to other PET bottles this one does not have a screw-cap, but a tear-off ring-pull closure.
The PET lite 9.9 carbonated is displayed together with the other winners in the iF online exhibition. Moreover, as from March 2014, it can be admired live as part of the iF design exhibition in Hamburg.
