Kraft paper
Description
A strong, coarse paper made from unbleached Sulfate pulp converted from wood pulp by the Kraft process. Kraft paper is water resistant and is normally brown in color, although some Kraft papers are bleached to produce white sheets. It is made in basis weights from 25 to 60 pounds. Kraft paper is used commercially for packaging and grocery bags. In painting conservation, strips of the strong paper have been used to attach the exterior edges of the painting in a temporary stretcher. Some commercial framing studios use the nonarchival paper to seal the back of framed photographs and prints. Unbleached kraft paper contains about 5% Lignin and will become brittle and acidic with age.
