In July, SIG launched the SIGNATURE PACK, the world’s first carton pack 100% linked to forest-based renewable raw materials. During the drinktec 2017, this innovation has now been awarded with the “Beverage Innovation Award 2017” in the category ‘Best carton or pouch’. The award is presented by every year since 2002.

Udo Felten, Manager Product Related Global Environmental Sustainability & Affairs at SIG, accepted the award. He answered 3 questions to SIGnals about the SIGNATURE PACK:


What was the motivation for developing the SIGNATURE PACK?

Udo Felten: Sustainable, plant-based packaging allows a consumer brand to demonstrate to the consumer – in a tangible and relevant manner – their long-term commitment to a sustainable future.

We want to offer our customers the most sustainable packaging solutions available in the market. Carton packs from SIG are already composed of up to 82% wood, a renewable raw material. The SIGNATURE PACK is, therefore, a logical next step to expand the renewable raw material basis to 100%.


How is the composite structure made up, specifically?

What’s different are the plastics in SIGNATURE PACK. They’re now linked to 100% forest material (tall oil) via mass balance systems. The plastics are certified under ISCC Plus or TÜV SÜD CMS71, respectively.

In addition, the aluminium layer of a conventional carton pack has been removed and replaced with a special PA (Polyamide) polymer barrier, which also has a link via mass balance to the renewable raw material wood. This layer in conjunction with other ultra-thin polymer layers (PE) make up 18% of the materials content. The spout is made of Polypropylene (PP) and/or HDPE – which is also 100% linked to plant-based renewable material.

The plastic producers guarantee, through strict certified traceability systems respectively, that a wood-based feedstock is replacing fossil feedstock in the manufacturing of the polymers used in our new packaging. Tall oil, obtained during the process of wood pulping, is used as the bio feedstock (bio-naphtha).


What is the advantage of the mass balance system?

The ambition of SIG is not to promote a niche market approach with only one or two available polymer grades. Rather it is to foster a transition from a conventional polymer industry towards a bio-based industry or economy. Conventional polymer producers run large scale continuous productions offering a range of different polymer grades. A substitution with renewable feedstock offers green polymer options all produced conventional plastic grades, which can be realised in an admixing manner due to supply limitations of bio-based materials.

Therefore, we support independently certified mass balance systems, which secure a link (and through credit allocation) between the procured renewable feedstock to polymer output via a virtual accounting system. By this, we follow the logic and acceptance of similar systems and approaches used in renewable energy, carbon trade, fair traded coffee and cocoa etc. In working closely with suppliers, we’re now able to offer a product that answers to industry needs, and to the growing environmentally-conscious consumers. Consumers, who are expecting sustainable products from brands they love.
