The Chemistry of Paper -

Kraft pulping was the complete opposite. The Germans created this type of pulping. When pulp is put through this process, the outcome is a much stronger and higher quality paper since most of the lignin is filtered out. The kraft pulping yields brown paper bags and paper equivalent to this strength. A lastly type of pulping was a chemical pulp.

Lignin - Wikipedia

Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily.Chemically, lignins are cross-linked phenolic polymers.
