From Wiki
Mechanical damage refers to the breakup of paper fibers or the impact of oxidation from metallic elements such as staples, clamps or clips. Also, the hardening or crystallization of adhesive tape used to repair a torn piece of paper can further tear or stain paper. Plastic elements, such as transparent or colored folders, damage documents due to their acidity and by encouraging humidity buildup. Mechanical damage is also caused by the tension on the paper due to bindings, clamps or presses, such as in classification binders. This tension is evidenced by tears, cracks, and the overall weakening of the paper.
