On 18 January 2022, SIG announced the launch of Signature Evo, claimed to be the world’s first aluminium-free full barrier packaging materials for aseptic carton packs. Signature Evo extends SIG’s lower-carbon aluminium-free packaging materials – already available for plain white milk – for wider use with oxygen-sensitive products such as fruit juices, nectars, flavoured milk or plant-based beverages.

By extending our Signature portfolio with Signature Evo – the world’s first aluminium-free packaging materials for aseptic cartons with full barrier protection – we are taking the next step in our aluminium-free journey and underlining our position as an industry leader in sustainable innovations,” said Ali Kaylan, SVP Innovation at SIG. “We are delighted to give our customers additional opportunities to bring low-impact packaging solutions to more categories and more consumers around the world. Sustainable innovations like this are central to SIG’s commitment to partner with customers and go Way Beyond Good for people and the planet.”

Industry-leading sustainable innovation

Signature Evo is the latest evolution in the Signature portfolio – offering of the most sustainable packaging materials available for aseptic carton packs. SIG led the industry with the first ever aluminium-free solutions for aseptic cartons. By eliminating the need for an aluminium foil barrier layer, combibloc Ecoplus cut the carbon footprint of SIG’s standard packaging material by 27% when launched in 2010. Signature 100 cut this further in 2017, offering a 58% lower carbon footprint than SIG’s standard packaging material by linking the polymers to 100% renewable forest-based materials via a certified mass-balance system1.

With more than 1.9 billion packs now sold with these aluminium-free long-life packaging solutions for liquid dairy products, SIG has built on this success to create the first full barrier aluminium-free solutions for aseptic cartons.

Signature Evo packaging materials are expected to offer a similar carbon footprint reduction to combibloc Ecoplus, to be confirmed through an independent, critically-reviewed life-cycle assessment. Like all SIG packs, Signature Evo is fully recyclable in existing recycling streams.

Extending aluminium-free solutions to more products

With barrier properties comparable to standard aseptic cartons that include an aluminium foil barrier layer, Signature Evo packaging materials ensure that even oxygen-sensitive products are protected over long periods of time without the need for refrigeration. This enables customers to bring the environmental benefits to many more food and beverage categories.

Signature Evo will initially be launched in the combiblocMini portion-sized format before being extended to other formats. It is suitable for both oxygen-insensitive products like plain white UHT milk and oxygen-sensitive products like fruit juices, nectars, flavoured milk or plant-based beverages.

Standing out with SIG’s sustainable packaging

Signature Evo enhances opportunities for customers to differentiate their products with an aluminium-free pack that offers both on-shelf appeal and stand-out environmental credentials.

In the future, it will also be available in more options such as Signature Evo 100 – SIG’s full barrier solution for aseptic carton packs linked to 100% renewable forest-based materials.

The announcement reinforces SIG’s position as the leading supplier of aluminium-free aseptic carton packaging solutions, and also underlines SIG’s commitment to offer the most sustainable food packaging solutions on the market as it goes ‘Way Beyond Good’ for customers, society and the environment.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
