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.
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.
Our work as part of the Aluminium Stewardship Initiative (ASI) seeks to address some of the issues described above at an industry level. In 2016, we were elected to the board of the ASI. Along with Rio Tinto Aluminium, BMW, Nespresso, WWF and the International Union for the Conservation of Nature, among others, we are working to establish a global standard that includes environmental and social criteria for all stages of aluminium production and transformation.
ASI formally launched its certification programme for the aluminium value chain in 2017. Read more ASI launches certification program
