Despite its low grammage, Koehler NexPlus Seal Pure 36 gsm has high strength and is ideal for further processing on commercially available packaging machines for horizontal packaging formats, such as flow packs and wrapping paper. 

The surface of the paper makes it suitable for flexo, digital, and gravure printing. Koehler NexPlus Seal Pure 36 gsm is ideal for primary or secondary packaging for food and non‐food products.

The low grammage of Koehler NexPlus Seal Pure 36 gsm helps to reduce the use of materials in its production, saving valuable resources without having to compromise on essential properties for packaging paper.

Joachim Uhl, director at Kehl. “The biggest challenge with production was the speed, as it was crucial that the paper remained stable at this speed, not only on our paper and coating machines but also on our customers’ packaging machines. Through a combination of our production line eight in Kehl and our colleagues’ expertise in the flexible packaging paper division, we were able to bring this paper onto the market.” 

Its low opacity means that the paper is already being used to package brochures for mailing. “You can see what's inside the packaging or scan a QR code through
it. This is what makes NexPlus Seal Pure attractive for the mailing of brochures. The fact that we use 100% certified virgin fibre pulp in production means that the paper is also suitable for food packaging and is already being used as secondary packaging,” said Christoph Wachter, director of the flexible packaging paper division at Koehler Paper. 

The research and development team from Koehler Innovation and Technology worked with the experts from Koehler Paper to develop the NexFlex product range, a 100% recyclable generation of flexible packaging paper.

The aim here is to replace plastic in packaging by using 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 is sustainable barrier paper with functional surfaces for product‐specific protection.
