Description

A strong, coarse paper made from unbleached sulfate pulp. The wood pulp is primarily obtained from pine trees such as the southern pine. Kraft paper is water resistant and is normally brown in color. 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. Kraft paper contains lignin and will become brittle and acidic with age.
