Pharmaceutical closure and corresponding manufacturing method

摘要

A pharmaceutical closure is made from rubber or thermoplastic elastomer and has an amount of TiO2 present in the closure. The closure has a marking made by laser thereon. A method for manufacturing the closure consists of producing a rubber sheet, forming a plurality of closures on the rubber sheet, with the closures remaining integrally connected with each other through remaining sheet parts, marking each of the closures with a laser marking, and separating the closures from each other by punching.
