Nampak unveils 'next generation' HDPE milk bottle

Milk bottle manufacturer Nampak Plastics has announced the launch of its “ultra-lightweight” and “next generation” milk bottle, due to start hitting supermarket shelves this summer.

The new bottle design, Infini, uses less material by having less defined corners, and has also repositioned the handle on the diagonal – without affecting strength.

As the manufacturer produces 2 billion HDPE milk bottles a year, the new bottle will soon find its way into the nation’s recycling bins and MRFs. But it will take a few years for its total production to move to the new lightweight version.

On average the new bottles will be on average 15% lighter, use 10,000 tonnes less plastic a year and save 23,000 tonnes of carbon a year. This will help Nampak’s dairy customers with achieving Government and industry targets such as Courtauld 2 and the Milk Roadmap. The move has cost Nampak around £9 million to implement the range and £1m developing the design.

Nampak business development director James Crick said: “Until now lightweighting has been achieved by simply using less material in making the standard bottle design, but there is a limit to how thin the walls can be and still be fit for purpose. What Nampak has done is to go back to the first principles and change the design of the bottle so it requires less material to manufacture.”
