The kraft in the paper world: A deep look into the universe of kraft paper
Have you ever been to a café or supermarket and carried your purchases home in a sturdy, ecological bag? Or have you ever received a package wrapped in sturdy brown paper? Probably yes. The paper you are holding is kraft paper. It is becoming increasingly popular in a world increasingly opting for sustainable and eco-friendly materials. But what exactly is this kraft paper?
The Substance of Starch: What is Kraft Paper?
Kraft paper, also known as kraftliner, is a speciality paper made from long-life pulp, mostly softwood. Its name comes from the German word "Kraft" which means "strength" and gives a direct indication of the impressive tear resistance and resilience of this type of paper.
Behind the scenes: The manufacture of kraft paper
The production of this type of paper begins with the selection of the right wood. Usually, softwood is used because its long fibres guarantee high strength of the final product. After removing the bark and other outer layers, the wood is chopped into chips. These wood chips are then cooked in what is known as the sulphate or kraft process. During this process, lignin and other binders dissolve, leaving behind pure pulp.
After the cooking process, the pulp is bleached and cleaned to remove any impurities that may remain. The cleaned pulp is then soaked in water to produce paper pulp. This mass is then fed through a paper machine, which removes the water and presses the material into thin sheets. After drying, the finished paper is wound up into large rolls, ready for shipping and further processing.

It is also used in a variety of ways in industry, for example as an intermediate layer when stacking products, as protective paper during shipping or as filling material in packaging.
