Dental Floss Bobbins are precision-wound thread packages used in floss dispensers, refill cartridges, floss picks, travel kits, and promotional oral care sets. WIRESUN winds custom dental floss bobbins according to customer drawings, samples, or product specifications, supporting different floss materials, bobbin formats, core types, winding lengths, outer diameters, and tension requirements.


Built with CNC precision winding equipment and controlled production processes, each bobbin is designed for dimensional consistency, accurate length per bobbin, and smooth snag-free payoff on automatic assembly lines. These bobbins are suitable for oral care brands, private label manufacturers, hotel and travel amenity suppliers, and dental clinics. Prototype development, sample validation, and mass production are available for OEM/ODM projects.
