On the inside of our aseptic cartons, a layer of aluminium eight times thinner than a human hair provides vital protection from oxygen and light, keeping perishable food safe without refrigeration and preservatives for months. Although this layer is minute, we are continually innovating to make it as thin as possible, while investigating alternative barrier materials.

​​​​​​​​​​​​​​​​​​The aluminium challenge

Aluminium is included in aseptic cartons because it prevents oxidation and light damage. However, its production can be associated with environmental and social issues, ranging from land use and hazardous by-products; to working conditions, health and safety. Furthermore, because aluminium is traded in an open market, it can be difficult to trace back to the original source. Addressing these challenges is complex and requires continuous research and innovation, as well as working with multiple stakeholders.

Multi-business partnerships​

As a founding member of the Aluminium Stewardship Initiative (ASI), we aim to address sustainability topics related to aluminium at an industry level. Along with Rio Tinto Aluminium, BMW, Nespresso, WWF and the International Union for the Conservation of Nature, we are working to establish a global standard that raises the bar for aluminium production, environmentally and socially.

In December 2017, the ASI released version two of its Performance Standard, meaning we can now become certified to that level in 2018. 

In parallel, all but one of our aluminium foil suppliers are becoming ASI members. This requires them to achieve certification standards within two years and demonstrates their commitment to socially and environmentally sustainable future for aluminium.
