First impressions can be tricky with boxes

Whoever thinks that kraft paper and kraft paper are the same thing may be quite mistaken. It is equally wrong that kraft paper must always be dark brown.

Nowadays, very good testliner papers (T1) are available, which are not behind kraft paper in appearance (e.g. colour). One should therefore not always go for the first impression. As in everyday life, this can often be deceiving.

The question then arises, how do I know that it is kraft quality and not testliner paper? Simple. Kraft paper is made up of long fibers, with the length of the fibers being secondary in testliner. If you tear the paper and find long, even brownish fibres, you can be sure that it is kraft paper.

Only one question remains: how is it possible that kraft paper is not always dark brown? Firstly, it depends on the type of wood that was used (softwood or hardwood) and then also, and more importantly, the proportion of recycled fibre used. Up to 30% recycled fibre is allowed in the production of kraft paper. By using different percentages, the colour ranges from dark brown to grey-brown.

However, all the typical characteristics of kraft paper, such as high tear, bending and compressive strength, high moisture resistance and good stackability, must be guaranteed.
