摘要

An embodiment of the present invention is directed to an earplug that includes a cylindrical body having a pair of faces positioned on opposite sides of the cylindrical body, and indicia printed on at least one face of the pair of faces. Other embodiments of the present invention are directed to a method and a system for producing the earplug having indicia thereon. The method includes forming the earplug with the cylindrical body and the pair of faces, and printing the at least one indicia on at least one face of the pair of faces. The system includes an extrusion machine configured to form the earplug, a smoothing roller configured to smooth the earplug, and a printing apparatus configured to print the indicia on the earplug. The earplug is formed silicone comprised of 60-90% vinyl stopped dimethypolysiloxane, 10-30% treated fumed silica and 0.5% or less of a fluoropolymer.
