Amcor has introduced a redesigned version of its UniPak 1kg dairy pot, delivering material reductions while maintaining the performance and durability required by high-volume yogurt and dairy applications.

Announced in Zurich on 26 March, the updated UniPak features a combined pot and lid weight of 31.6g, offering up to a 9% reduction in carbon emissions compared to its predecessor, based on anticipated production volumes.

The move reflects ongoing industry demand for lightweighting solutions that do not compromise product protection or operational efficiency.

The container is manufactured from polypropylene, making it recycle-ready in markets with appropriate infrastructure. Despite the reduced material usage, the pot retains its structural integrity throughout the supply chain and is designed for convenient handling in consumer use.

Key functional enhancements include a compression-moulded, liquid-tight lid that remains securely fastened under pressure, alongside improved tamper-evidence features to enhance product security. The format also supports efficient palletisation and includes a protective collar to stabilise the pack and safeguard the lid during transport.

Katrina Burrett, product line director for containers and reusables at Amcor, said: “The 1kg size is especially popular in dairy, and our new UniPak enables brand owners to combine high performance with sustainability goals. It demonstrates that meaningful lightweighting doesn’t have to come at the expense of strength or functionality.”

Designed with flexibility in mind, UniPak is compatible with a wide range of decoration technologies, including in-mould labelling, and is available in multiple shapes and sizes. Shared lid diameters across formats aim to simplify inventory management and streamline supply chains for dairy producers.

The launch reinforces Amcor’s broader strategy to deliver packaging solutions that balance sustainability, functionality and operational efficiency for food and beverage manufacturers.
