The Origins of Kraft: From German Strength to Global Recognition

Kraft’s story begins in 1879 with Carl Dahl, a German chemist who developed the kraft process for treating wood pulp. This revolutionary process used a combination of sodium sulphide and white liquor to break down wood chips into strong, long cellulose fibres.

kraft paper roll is made from wood pulp treated with chemicals to remove lignin. The substance binds wood fibres together. This process leaves behind cellulose, which is the primary component of paper and provides strength and durability. The resulting pulp, unlike mechanical pulping methods, yielded a much stronger and more durable paper.

The Kraft Process: Unpacking the Science Behind Strength

As we know, kraft is the key to processing kraft paper bags uniquely. Now we can discuss the whole process of kraft paper. How to separate it from the wood pulp. Carl F. Dahl of Germany in the 1880s found ground pulp for the first time and treated this cellulose pulp with certain chemicals like sulphide that increase the strength of the paper. Here are some steps on how to prepare the kraft material from cellulose pulp.

Wood Chipping
Digestion
Washing and Screening
Bleaching
Sheeting and Drying

The kraft process, unlike mechanical pulping, preserves the strength of the cellulose fibres. This resulting paper has the properties of superior tear resistance, tensile strength, and overall durability.
