The Tamper-Resistant Vinyl (B-351) is designed to fracture easily in order to show signs of product tampering and to prevent on-piece label removal. High-performance white matte vinyl with permanent adhesive is ideal for applications that require resistance to product tampering. A ribbon is required to print this material. Use Part Number IP-R6202 for the BradyPrinter i5100 or BRADY IP Series Label Printer; use R6202 for a different printer.
