Sidel partners with coca-cola

In order to develop a new design for Fanta bottle, Sidel has collaborated in the new “spiral” PET bottle project from The Coca-Cola Company (TCCC).

 

“After years of success in the international soft drinks market, the Fanta Splash shape had effectively become owned by the carbonated soft drinks category rather than the brand.

 

Gregory Bentley, Coca-Cola Packaging Engineer in charge of global project coordination said, “This is quite a standard occurrence over the life cycle of a brand which inevitably evolves over time. This meant it was the right time to redesign the bottle with an impactful shape to make it stand out once again on the shelves.”

 

“Working closely with Leyton Hardwick and his team at Drink Works who were the winning agency in a 5 way pitch and supported by the Fanta packaging team network “We established a global network where it was possible to gather up-to-date packaging mix information, specific market requirements and on-going feedback on suitable design routes”, continues Bentley.

 

“By embedding the supplier’s knowledge and experience from the very first steps of this journey, we have ensured viable bottle forming, filling and performance. It was great to count on Sidel as part of this project as a very skilled and responsive partner.”

 

The new bottle shape required precise understanding of how PET behaves under pressure, particularly with regard to how the carbonation of the beverage can potentially deform the bottle sections, which could lead to the drink spilling. Just like its predecessor, the new bottle was to be produced to be 100% recyclable.

 

The new creative and differentiating bottle in PET designed by Drink Works represents a “rule-breaker” in terms of bottle design for CSD (carbonated soft drinks).

 

It features a spiral, inspired by the twisting of an orange to release its juice. It is based on a series of ribs decorated with small bubbles, including a torsion in the bottom half. This spiral gives the Fanta bottle an unusual, asymmetric structure which presented a real challenge in terms of developing a container able to withstand deformation and stability issues.

 

“We were championing this spiral shape, which has the accolade of being truly unique in the world of carbonated packaging designs for containers in PET, and Sidel supported us to overcome the challenges that the design presented,” says Bentley.

 

Jérome Neveu, packaging expert at Sidel said, “It is definitively critical that all opposing sides of the bottle have the same developed length to avoid issues with perpendicularity. We optimised the grip profile and the angular base orientation to retain the bottle geometry once filled.”

 

Bentley concludes: “the final PET bottle design has been fully tested, making sure the vertical growth under pressure is perfectly controlled and that the container meets all Coca-Cola quality and performance requirements. The physical strength of the new bottle is as good as the previous Fanta Splash bottle. Other line stability tests were also conducted by Sidel, achieving suitable results for high speed filling.”
