SIG announced another industry first for responsible sourcing by purchasing 100 % of the aluminium for SIG aseptic carton packs with certification to the Aluminium Stewardship Initiative (ASI) standards globally from January 2023. SIG is the only packaging provider to offer aseptic cartons with ASI-certified aluminium and enable customers to include the ASI label on its packs.

SIG has led the way in offering the world’s first packaging materials without an aluminium layer for aseptic cartons since 2010, including a full barrier solution without an aluminium layer launched in 2022. But these are not yet available in all formats and many of SIG’s aseptic carton packs still require an ultra-thin layer of aluminium foil to protect the food inside.

Through ASI certification, SIG is demonstrating its commitment to source aluminium for its packs responsibly. ASI sets leading standards for responsible aluminium production and sourcing, covering a broad range of ethical, environmental and social topics, including specific limits on carbon emissions in the production of aluminium.

By requiring all its aluminium suppliers to meet ASI standards, SIG is helping to improve performance in supply chains and drive lower-carbon aluminium production. This in turn supports reductions in the value chain carbon footprint for SIG and its customers.

SIG announced another milestone in its ambition to go Way Beyond Good for society and the environment by offering ASI-certified aluminium as standard for all SIG packs in Europe.

SIG is the first in the industry to obtain certification to both the ASI (Aluminium Stewardship Initiative) Performance and Chain of Custody standards and is the only aseptic carton producer to offer ASI-certified aluminium in its packs.

The first ASI-labelled cartons were launched by customers such as B-Better® (from Unilever’s Better Future Platform), Riedel and DRINKS3 in 2019. Now, ASI-certified aluminium will come as standard for all SIG packs in Europe.

SIG is the first in the industry to enable customers to demonstrate their commitment to responsible aluminium sourcing using the Aluminium Stewardship Initiative (ASI) certification.

Added value through responsible sourcing

SIG offers the world’s first aseptic carton packs that use foil certified to the ASI standard. This add value for customers, brands and retailers by promoting responsible sourcing throughout the value chain – from suppliers all the way through to consumers.

SIG customers also have the option to include the ASI label on packs to show consumers that SIG sources responsibly the aluminium it uses in the cartons – in the same way they can already include the FSCTM label on any SIG pack to show that the liquid paper board comes from responsible sources.

First certification for responsible aluminium

SIG was the first in the industry – and one of the first companies in the world – to achieve certification to the ASI Performance Standard Material Stewardship Principle at the corporate level, together with the ASI Chain of Custody certification for its production site in Austria. The company has now extended ASI Chain of Custody certification to all its carton sleeve production sites in Europe.

The ASI certification enables companies to audit the aluminium supply chain against strict standards on a broad range of ethical, environmental and social topics. Previously, there was no such certification available to certify the ultra-thin layer of aluminium foil used in SIG packs. SIG’s ASI Chain of Custody certification has made it possible for the ASI Standard to be put into practice for the first time in aseptic carton packs.

Europe-wide ASI certification is an important step towards SIG’s target to source 100 % of its key materials from certified sources as part of its ambition to go Way Beyond Good for the environment and society.
