The ILS labelling system for signs is a DIN A5 polyester film for inkjet and laser printers with high temperature resistance. (If laser printers are used, please check whether self-adhesive films with a thickness of 250 m can be printed.) The adhesive coating 3MTM9471 LE is UL approved (reference number MH 11410). The sheets are available either uncut for making individual adhesive signs or pre-punched with 23 strips (each 6 x 191 mm) for labelling 11 devices (1-module) per strip.
