Koehler Paper, part of the Koehler Group, has teamed up with chocolate manufacturer nucao in a step toward boosting sustainability on the chocolate shelf. The new chocolate bars from Leipzig-based company nucao are not only organic, vegan, and fair trade, they also use 100% paper packaging. The ‘Koehler NexPlus Advanced’ flexible packaging paper from Koehler Paper provides ideal protection for the chocolate thanks to its excellent oxygen, mineral oil, and grease barrier properties. 

The nucao bars are available from German retailers in four varieties: ‘Roasted Hazelnut Butter,’ ‘Almond Butter & Sea Salt,’ ‘Salted Caramel,’ and ‘Crisp & Crunch.’ Koehler Paper will be presenting the chocolate bars and other applications for paper packaging at the Koehler Group booth A20 in Hall 4 at the drupa trade show in Düsseldorf from 28 May to 7 June. 

Koehler NexPlus suited for reuse 

When developing ‘Koehler NexPlus Advanced’ flexible packaging paper, the focus was on making it recyclable and ensuring it offered outstanding product protection. As a result, the paper can be recycled as part of a standard paper recycling process and can often be reused. This is also certified by the Papiertechnische Stiftung (PTS, Paper Technology Foundation) and environmental service provider Interseroh. 

“The paper fibers can be reused up to 13 times. Working with nucao, a pioneer in the chocolate segment, we want to show that we are capable of putting the circular economy into practice and making sensible and sustainable use of the raw materials available to us,“ says Christoph Wachter, Director of the Flexible Packaging Paper division at Koehler Paper, as he explains the sustainability aspect of this flexible packaging paper. Compared to conventional plastic packaging, flexible paper packaging also significantly reduces the carbon footprint. 

With the 360° sustainability approach that nucao takes to its chocolate bars, the company is not only advocating for a deforestation-free supply chain and fair remuneration for cocoa farmer families, but it is also taking a stand in the fight against plastic waste by using eco-friendly packaging—this is a never-seen-before combination of USPs in the supermarket chocolate shelf segment. Mathias Tholey, co-founder of nucao, “Many chocolate manufacturers focus on one green attribute, but fair trade, organic, or vegan alone is not enough to ensure your business is truly sustainable. You need the full package! Having worked with Koehler Paper to develop our recyclable paper packaging, we know from experience that they are a reliable and trustworthy partner.” 

Innovative paper solutions with NexFlex from Koehler Paper 

The research and development team from Koehler Innovation & Technology worked with the experts from Koehler Paper to develop the NexFlex product range, a unique and 100% recyclable generation of flexible packaging paper. The aim here is to replace plastic in packaging by using so-called barrier paper wherever possible. The range covers a broad spectrum: It includes standard coated and uncoated paper used in laminates for pouches, sachets, and other applications, making them suitable for a wide range of packaging for food and non-food products. 

The next generation of paper for flexible packaging are sustainable barrier paper with functional surfaces for product-specific protection (Koehler NexPlus). The NexFlex product family also includes paper coated on one side with good dimensional stability and high smoothness (Koehler NexCoat), as well as uncoated paper with a natural appearance (Koehler NexPure). Various flexible packaging paper from Koehler Paper were awarded the ‘Made for Recycling’ seal by the environmental service provider Interseroh. 

The Koehler Group was founded in 1807 and has been family-run from that moment to the present day. The group’s core business activity lies in the development and production of high-quality specialty paper. This includes—among others—thermal paper, playing card board, beverage coasters, fine paper, carbonless paper, recycled paper, decor paper, wood pulp board, sublimation paper, and also innovative specialty paper for the packaging industry since 2019. 

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are growing similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground. Share your thoughts and plans to inspire and mobilize our editorial and advertising teams!
