Kraft paper, sometimes mistakenly referred to as 'craft paper' by some, was named after the German word kraft, meaning 'strength,' which refers to a specific type of pulping process that ensures strong paper. Developed in 1879 by Carl F. Dahl, a patent was issued five years later, and the first kraft paper-making company opened its doors in Sweden in 1890. Combined with the invention of the recovery boiler in the early 1930s, kraft paper production entered a new, more efficient and environmentally-friendly stage.
