Sidel’s returnable bottle purpose‑built for water
Sidel has unveiled a new returnable PET bottle designed specifically for still water, giving producers a lightweight, fully recyclable alternative to formats originally engineered for carbonated products.
The launch marks a significant shift in returnable packaging for one of the highest‑volume beverage categories, as brands and retailers look for solutions that cut material use, reduce waste and support circularity.
The new Returnable PET – Still Water bottle removes the structural constraints associated with carbonation, allowing Sidel to optimise the design around the needs of still water alone. The result is a bottle that is 10% lighter than the lightest 1‑litre returnable carbonated water bottles currently repurposed for still water, while still delivering the durability required for up to 25 washing cycles.
Jerome Neveu, packaging and mold product manager at Sidel, said the development responds directly to rising expectations around reuse and tightening regulatory pressures across Europe. He noted that still water producers have long been limited to returnable bottles adapted from carbonated formats, restricting design freedom and lightweighting potential.
By contrast, the new bottle opens up fresh opportunities for brands. Available in cylindrical or distinctive square shapes from 0.5 to 2 litres, the design can be customised to reflect a brand’s single‑use identity while offering the environmental benefits of a returnable system. Textured surfaces help preserve a premium look and feel throughout repeated reuse cycles, supporting applications in retail as well as HORECA settings where aesthetics matter.
The bottle is fully compatible with existing PET recycling streams, enabling bottle‑to‑bottle circularity at the end of its service life, and can be produced across Sidel’s EvoBLOW blow‑moulding range.
For still water manufacturers, the launch represents a rare combination of lightweighting, durability and design flexibility in a returnable PET format — a timely development as the sector accelerates its shift toward lower‑impact packaging systems.
