Packaging Solutions

Koehler Paper has launched an ultra lightweight heat sealable flexible packaging paper – Koehler NexPlus Seal Pure 36 g/m2. Despite its low grammage, the paper 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 paper’s outstanding surface makes it suitable for flexographic, digital, and gravure printing.

The low grammage helps to reduce the use of materials in its production, saving valuable resources without having to compromise on essential properties for packaging paper. ‘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 cutting edge production line 8 in Kehl and our colleagues’ expertise in the flexible packaging paper division, we were able to bring this paper onto the market,’ explained Joachim Uhl, Koehler Paper mill director at Kehl.

Its low opacity means that the paper is already being used to package brochures for mailing. ‘You can see what is inside the packaging or scan a QR code through it. This is what makes Koehler NexPlus Seal Pure so 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, as he explains the applications of this flexible packaging paper.

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 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).
