Sterilization Inks are used to verify whether a material has been adequately exposed to a sterilization process. Chroma Inks USA’s sterilization inks are used in the manufacturing of labels, pouches, tapes, and other applications. Our sterilization ink product line includes inks that produce color change upon exposure to saturated steam, ethylene oxide, formaldehyde, dry heat, plasma, ozone, or peracetic acid. Other benefits of our inks are:

  • Flexibility – Inks can be customized for use in different printing techniques such as flexography, rotogravure, and screen printing. Inks are available in a range of colors – the tables below contain more information on the different color change combinations available for different sterilization processes. Our inks can be used with a variety of substrates including Tyvek, paper, films, and tapes.
  • ISO 11140-1 Compliance - All inks are designed to function as class 1, 2, 4, and 6 process indicators.
