Sidel has introduced Nitro Square, a new high-performance square bottle design for still water using liquid nitrogen dosing.


According to Xavier Monnier, Sidel’s packaging innovation polymer expert, the nitrogen-dosed water market has so far been dominated by cylindrical bottles, as this shape naturally accommodates the internal pressure of the 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," he said.


The new design balances rigid structural sections with flexible, pressure-absorbing surfaces to maintain the square shape while ensuring resistance and stability. It also incorporates Sidel’s StarLITE-R Nitro base, designed to enhance impact resistance and improve bottle stability.


Sidel said the design is easy to customise for different brand positions – from premium to mainstream – and is available in both single- and multi-serve formats.


The bottle is compatible with Sidel’s existing production systems, including Universal, Series 2 and EvoBLOW machines, allowing production speeds of up to 2,600 bottles per hour per mould.
