Below is a list of Mailing Tubes manufacturers from Menomonee Falls, Wisconsin. Mailing tubes are cylindrical cardboard containers manufactured primarily from wood pulp fibers which are used, among many other applications, for shipping and mailing. The cardboard is cut into ribbons which are combined with adhesives to increase the durability of the material. The ribbons are then wound around mandrels into a hollow tube or cylinder according to the desired diameter and length.
