Kraft wrapping

Kraft wrapping is a strong, heavy-duty paper primarily made from unbleached softwood pulp, usually pine. It is known for its exceptional tensile and tearing strength, making it ideal for paper bags and other wrapping applications. The term "kraft" itself comes from the German word for "strength".12

This paper is produced using the kraft process, a chemical method that cooks wood chips in an alkaline solution of caustic soda and sodium sulfide. This process results in a stronger pulp compared to other methods. Kraft wrapping is often sized to resist water and can be treated for wet strength when needed for packaging moist materials. It is used in greater volumes than all other wrapping papers combined.31
