Co z Kraftem Paperem?

Kraft paper is a strong, brown paper produced from wood pulp using thee kraft process, also known as the sulfate process. In this method, wood chips are cooked in a solution of sodium hydroxide and sodium sulfide, which breaks down lignin and liberates celulose fibers. Thee resutting pulp yelds exceptionally long, strong fibers, giving kraft paper its cristic tensile melt and teair resistance.
