Packaging machinery supplier Sidel has introduced Nitro Square, a square-shaped PET bottle for still water with liquid nitrogen dosing.
The design combines rigid features with more flexible, pressure-absorbing surfaces to maintain the bottle’s square profile while allowing for new designs.

The bottle incorporates Sidel’s wave-shaped StarLITE-R Nitro base, which enhances stability and drop resistance.
Nitro Square is offered in single and multi-serve formats and can be easily customised to different brand positioning, from premium to mainstream and affordable tiers.
The bottle can be produced on Sidel’s existing equipment lines — Universal, Series 2 and EvoBLOW — at up to 2,600 bottles per hour per mould.
Sidel packaging innovation polymer expert Xavier Monnier stated: “The nitrogen-dosed water bottle market is largely dominated by cylindrical forms, as this is the natural shape created by the internal pressure of the bottle’s contents.
“Nitro Square allows manufacturers to elevate their brands with a unique square design that stands out on the shelf, secures its shape and performance across the supply chain and is valid for rPET.”
The latest announcement follows recent Sidel projects and expansions.
In Catania, Sicily, Sibeg — the Coca-Cola Company’s authorised bottler in the region — has commissioned its first aseptic PET bottling line incorporating Sidel equipment. The new line, with an 18,000 bottles per hour capacity, features Sidel’s Aseptic Combi Predis, EvoFilm Stretch and PalKombi systems.
Sidel has also opened an office in Lagos, Nigeria to support its West African operations and sustainable packaging initiatives. The new hub in Phoenix, Ikeja, will improve project management, engineering and customer service for clients in Nigeria, Ghana, Côte d’Ivoire and neighbouring markets.
