Kraftliner, also known as craft paper or kraft paper, is a particularly strong paper that plays an important role in the printing and packaging industry. The name ‘Kraft’ comes from the German word for ‘strength’, which describes the main property of this material well. It is mainly made from wood fibres, which are prepared in a special process known as the Kraft process. In this process, the wood chips are chemically treated to separate the cellulose fibres from the lignin. The result is long, resistant fibres that give the paper its strength.
This paper has a natural brown colour, but can also be bleached or dyed in different colours. It is very tear-resistant and resistant to mechanical stress, which makes it ideal for packaging heavy or bulky goods. It is often found as the outer layer of corrugated cardboard used for transporting goods.
Another common application for kraft paper is carrier bags and envelopes. Carrier bags made from kraft paper are very popular in the retail sector as they are strong enough to transport purchases home safely. These bags are often printed to display a shop’s logo or advertising message. Kraft paper envelopes are also useful, especially when it comes to sending documents and smaller items securely.
Kraft paper can also be found in labels and tags, especially in the fashion and food industries. They give products a rustic and natural look. Kraft paper is also popular in the printing sector, especially for printed matter that is intended to convey an environmentally friendly or handmade impression. Although the print quality on the rough surface is not as good as on smoother papers, the natural look has its own charm.
A major advantage of kraft paper is its environmental friendliness. It is fully recyclable and biodegradable. Many manufacturers make sure that the wood used comes from sustainably managed forests, and unbleached kraft paper also saves on chemicals, which further reduces the ecological footprint.
To summarise, kraft paper is a strong, versatile and environmentally friendly material that is used in many areas of the printing and packaging industry. It offers practical benefits and aesthetic qualities that make it a popular choice for businesses and consumers who value sustainability.

New iPhone colour measuring devices: xade nano+ in test
A new generation of colour measuring devices is entering the market: in contrast to the classic measuring devices, which are available as a fully encapsulated system either as a colourimeter or as a spectrophotometer, and then supply the data to a computer via an interface or app or display it directly, the new generation of colour measuring devices consist only of lighting and software, with the optics of a modern iPhone from Apple being used as the sensor. Until now, there have been two categories of measuring devices on the … read more
We passed the first proof certification for the 7C proof under FOGRA55
A few days ago Proof GmbH was the first company to be certified for proofing for the new 7C exchange colour space FOGRA55. Fogra has developed characterisation data for extended multicolour printing with the printing colours CMYKOGV – i.e. cyan, magenta, yellow, black (contrast), orange, green and violet – FOGRA55 as part of a research project over the past few years. The characterisation data and the ICC profile Ref-ECG-CMYKOGV_FOGRA55_TAC300.icc have been published on the Fogra website in recent weeks. We have now carried out the certification via GMG ColorProof, as … read more
New certified proof papers at proof.de
In recent years, various problems have arisen with our previous proof paper supplier. On the one hand, we sometimes had to wait more than three months for paper deliveries; on the other hand, we sometimes had significant problems with batch-to-batch discrepancies, surface defects and much more. After lengthy deliberations, we decided in December to replace all the paper. We therefore received pallets of new paper at the turn of the year, which we are now gradually incorporating into our production. There will be no hard cut, but the new papers … read more

MYIRO-9: New Spectrophotometer from KonicaMinolta in action
Over the last few months, we at Proof.de have been thinking about further improving our already very good colour measurement technology in terms of speed and measurement precision. Relatively quickly it became clear that only two devices would come into question: The KonicaMinolta MYIRO-9, the successor of the former FD-9, or the X-Rite ISIS 2 XL. The starting point: Since we at Proof GmbH have 5 proofing devices, the calibration of targets for profile optimisation is a time-critical undertaking for us. Therefore, we had been looking around for an upgrade of … read more
