Koehler Paper, part of the Koehler Group, is expanding its offerings in the NexPlus group of innovative flexible packaging paper products. With its excellent oxygen, grease, and mineral oil barrier properties, the product is suitable for metallizing, making it perfect not only for packaging for food such as chips, energy bars, energy powders, and coffee, but also for non-food products such as cosmetics in powder or solid form. 

With this step, Koehler is expanding its portfolio of fiber-based flexible packaging paper. Koehler Paper is presenting the product concept to the public for the first time ever at the Interpack trade show in Düsseldorf from 4 to 10 May at stand D42 in Hall 8a.

Metallized packaging paper offers one-of-a-kind barrier properties while not compromising recyclability 

Together with Nissha Metallizing Solutions, Koehler Paper has developed a premium product that is made 100% with virgin fiber pulp from certified sustainable forestry and controlled sources and that is designed to be recyclable in conformity with the latest testing methods. In comparison to conventional plastic packaging, the flexible packaging paper reduces carbon footprints significantly and contributes to a sustainable circular economy. 

“The first packing machine performance tests have yielded very promising results. The barrier properties that provide resistance to oil and grease in the bags that were produced have turned out to be particularly outstanding,” explains Christoph Wachter, head of the Flexible Packaging Paper division at Koehler Paper, when going over the initial test results for the innovation. Just like with all other Koehler NexPlus paper products, this innovative product can be heat sealed too. In addition, it is characterized by outstanding strength, resistant barrier properties, and excellent printability. “The metallizing boosts the barrier properties to a whole new level, enabling us to guarantee excellent product protection and extraordinary product quality,” adds Nissha Metallizing Solutions CEO Giorgio Boss. 

Sustainable packaging: Innovative paper solutions with ‘NexFlex’ from Koehler Paper 

With the NexFlex product range, Koehler Paper has developed a unique and 100 per cent recyclable generation of flexible packaging papers. 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 papers 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 papers for flexible packaging are sustainable barrier papers with functional surfaces for product-specific protection (NexPlus). 

The NexFlex product family also includes papers coated on one side with good dimensional stability and high smoothness (NexCoat) as well as uncoated paper with a natural appearance (NexPure). Various flexible packaging papers from Koehler Paper were awarded a score of 19 out of a possible 20 points by the environmental service provider Interseroh, along with the ‘Made for Recycling’ seal. 

Nissha Metallizing Solutions is a leader in the production of metallized paper and paperboards for flexible packaging and labels (wet glue labels, pressure sensitive labels, general labels and in-mold labels). Metallized paper is a recyclable paper-based monomaterial and thus a sustainable alternative to foil or film.
