A strong focus on sustainable packaging innovation has produced a decade of industry firsts from SIG. Our SIGNATURE portfolio is delivering for our business, our customers and our planet.

Environmental considerations are central to product development at SIG as we create solutions to help customers meet growing consumer demand for sustainable packaging and adapt to an ever-changing world.

Fully recyclable and mainly made from renewable paper board, our standard packs have a 28% to 70% lower carbon footprint than alternative types of packaging. Over the past 10 years, we have been leading the industry with a series of sustainable innovations that reduce the impact of our packs even more.

Our pioneering combibloc ECOPLUS packaging material, launched in 2010, is the world’s first aluminium-free aseptic carton solution. By eliminating the need for an aluminium foil barrier layer, it reduces the carbon footprint of our standard packs by 27%.

Following this breakthrough, we went on to develop SIGNATURE 100, the world’s first aseptic carton solution linked to 100% renewable materials. Launched in 2017, our SIGNATURE 100 packaging material is aluminium-free and links the polymers in the pack to renewable, forest-based feedstock1. It cuts the carbon footprint of a standard pack by 58%.

SIGNATURE 100: making the connection to 100% forest-based material

SIGNATURE 100 is the world’s first aseptic carton solution linked to 100% renewable, forest-based raw materials.

Aluminium-free. 82% renewable paper board. Polymers linked to 100% forest-based materials.

With combibloc ECOPLUS and SIGNATURE 100, we are offering the most sustainable packaging solutions on the market for UHT milk producers.

Our SIGNATURE Full Barrier packaging material enables other customers to get the benefits of polymers linked to 100% renewable feedstock, while maintaining the ultra-thin aluminium foil barrier layer needed to protect more sensitive food products like juices and water. This cuts the carbon footprint of our standard packs by 45%.

SIGNATURE enables us to offer the most sustainable packaging solution, which at the same time guarantees the premium quality expected by our valued CoolBest customers. Switching to this new carton underlines our leading role in sustainability within the fruit juice industry.”

The polymers used in our SIGNATURE 100 and SIGNATURE Full Barrier packaging materials are linked to renewable materials via an innovative mass balance approach.

Independently certified to ISCC PLUS, this system ensures the amount of forest-based raw materials we need are mixed in with conventional fossil-based materials to produce polymers to the high grade required for aseptic food packaging.

We use the same ISCC PLUS certified mass balance approach to link the polymers used in our SIGNATURE Circular packaging material to 100% post-consumer recycled plastics.

The mass balance system supports a transition from fossil-based to renewable or recycled raw materials within the conventional and highly efficient polymer industry. This approach is endorsed by The Ellen MacArthur Foundation as a way to advance the circular economy.3

From plastic to paper straws

SIG was the first in the industry to offer a paper straw solution for aseptic cartons. We launched both straight and U-shaped paper straws in 2019.

“At Intermarché, our commitment to sustainable development is a priority. We decided early on to introduce SIG’s paper straw solution for aseptic carton packs to offer consumers a more sustainable alternative to plastic straws, while maintaining the on-the-go convenience of small-size packs.”

We are going further. Our mission is to create food packaging that makes the world a better place. And our continued focus on sustainable innovation will help us drive progress on this journey WAY BEYOND GOOD.
