Production Process and Characteristics of Kraft Cardboard

Kraft paper is darker than other types of paper or paperboard, being much more resistant as well. During the kraft paper pulping process, most of the lignin present in the wood is removed. And it is the low levels of lignin - an amorphous three-dimensional macromolecule associated with cellulose - that make paper resistant.

Although it is darker, kraft can be lightened for the manufacture of high-quality packaging, whose resistance to yellowing is fundamental.
