SIG sells over 150 million packs of aseptic carton packaging material

SIG has now sold over 150 million packs with its award-winning SIGNATURE, the world’s first aseptic carton packaging material linked up to 100% to renewable materials.

“SIG’s ground-breaking SIGNATURE is a great success, with over 150 million packs sold,” said Alina Theissen Hageresch, SIG’s marketing manager, Sustainability and Responsibility Europe. “Increased uptake shows that its strong environmental credentials offer customers an answer to consumers wanting more sustainable packaging alternatives as they seek to do their part for a low-carbon future.”

Consumers’ priorities are changing: a clear majority (73%*) now say they would change their consumption habits to reduce their environmental impact. As brands seek to meet demand for more sustainable products, their choice of packaging has a critical role to play as the first key touchpoint for consumers.

SIG’s standard carton packs, made with around 75% renewable paper board from FSC-certified sustainable sources, already offer a significantly better environmental performance than alternative types of packaging. The carbon footprint of a carton pack is up to 70% lower than plastic or glass bottles.

Launched in 2017, SIG’s innovative SIGNATURE packaging material links the polymers used to 100% forest-based renewable materials via an independently certified mass balance system. SIG chose tall oil – a residue extracted from wood in the paper making process – as the forest-based feedstock. It is a by-product from another industry rather than an agricultural crop requiring land and resources that could be used to produce food. An independent lifecycle assessment shows that SIGNATURE reduces the carbon footprint of carton packs even further – by 45% to 58% (European average) depending on the option selected (more information at

SIGNATURE is available in two options to meet demand for sustainable packaging solutions across all market segments.

The aluminium-free SIGNATURE 100 for dairy products is the world’s first aseptic carton packaging material linked to 100% forest-based renewable material. SIGNATURE Full Barrier includes an ultra-thin layer of aluminium, certified against the Aluminium Stewardship Initiative (ASI) standards, to protect products like orange juice that are more sensitive to light and oxygen.

The European and North American markets are pioneering the shift to more sustainable packaging solutions. Early adopters of SIGNATURE include Unilever’s B-Better in Belgium, Candia in France, nutpods in the USA and Water Cubed in UK.

“B-Better water was launched with strong brand values: help consumers to be good to themselves and do better for the planet,” said Hélène Esser, B-Better co-founder and marketing manager, Refreshments at Unilever. “SIGNATURE’s unmatched environmental credentials, combined with SIG’s unique bottle-shaped combidome carton, align perfectly with our strapline: ‘It’s a start for less plastic and a better planet’.”

Growing demand for SIGNATURE packaging material linked up to 100% to renewable materials is the latest milestone in SIG’s journey to go ‘Way Beyond Good’ by putting more into society and the environment than it takes out.

Sustainable innovation is central to this ambition and SIG has achieved a host of other industry firsts: first to enable customers to put the FSC™ label on any of its packs, first to offer aluminium-free aseptic carton packs, first to offer a paper straw solution for aseptic carton packs, first to offer carton packs with responsibly-sourced ASI-certified foil and, most recently, first to offer cartons made with recycled plastics.
