PURPOSE: To obtain a woven or a nonwoven fabric packaging material excellent in rust preventing effects and physical properties in order to package various metallic products requiring rust prevention.

CONSTITUTION: This woven or nonwoven fabric for packaging a metallic product comprises synthetic fibers containing a water-soluble glass powder and a suitable well-known vaporizable rust preventing agent. Split yarns of a synthetic resin film or sheet containing the water-soluble glass powder and the suitable well- known vaporizable rust preventing agent may be used as the synthetic fibers. Furthermore, a coating layer containing the water-soluble glass powder and suitable well-known vaporizable rust preventing agent may be formed on the surface of a woven or a nonwoven fabric made of the synthetic or natural fibers.
