Ultraviolet lasers are used throughout the medical device manufacturing industry for creating smooth to the touch, “cold markings” on plastics. Strict FDA and GS1 regulations require device manufacturers to label their products with unique device identifiers (UDI), such as 2D data matrices, manufacturer date, serial numbers, device identifier (GTIN), and more. Markings must be machine and human readable, as well as, smooth to the touch so bacteria cannot accumulate. These laser markings on medical components must withstand daily usage and consistent cleaning requirements. The photochemical alteration of the plastic using UV lasers is perfect for meeting UDI marking standards.
