Innovation - Pioneering packaging for milk 30/09/2011

This Spring saw the launch of another major innovation for Tetra Pak: Tetra Evero Aseptic™ 1 litre, the world’s first aseptic carton bottle for milk.

Our ground-breaking new packaging combines the easy handling and pouring of a bottle with the environmental and cost advantages of a carton, bringing compelling benefits to producers, retailers and consumers. It can also keep products fresh for up to six months due to an innovative sterilization process.

We developed Tetra Evero Aseptic through a blend of thorough market analysis and pioneering production techniques. We designed a range of different concepts and then developed candidate packages, which we tested through intensive market research. In this testing, consumers showed a strong preference for the Tetra Evero Aseptic and praised its handy shape, easy pouring and high-quality feel.

The package and its filling machine, the Tetra Pak A6 iLine, are covered by 14 design and application patents. Technological developments include an industry first ‘gas phase’ sterilisation technique and advanced injection moulding technologies to fuse the top, carton sleeve and capped neck into a ready-to-fill package. In addition, the Tetra Pak A6 filling machine requires just half the space of an aseptic PET line.

Tetra Evero Aseptic also offers a wide range of environmental benefits. The paperboard in the package is made from renewable wood fibre harvested from forests that are certified by the Forest Stewardship Council (FSC) and other responsible sources. And we have plans to reduce the environmental impact still further. Next year, we will introduce a separable top, so that the cap can easily be separated from the carton sleeve for easier recycling. And in the future we will be making the neck and cap from renewable polymer, as part of our aim to offer a 100% renewable Evero Aseptic package.

We are initially aiming Tetra Evero Aseptic at the ambient white milk market, including non-oxygen sensitive milk enriched with calcium, proteins, fibres (inulin), vitamins A and D and some minerals. This will soon expand to cover a wide range of beverages, including flavoured milk, cream and oxygen sensitive milk.

We have supported the launch with a promotional campaign – ‘Designed for Life’ – to emphasise how the packaging has been designed to make people’s lives easier.
