Self-laminating labels made of material 323 are designed for use in heavy-duty conditions. They have excellent chemical and high-temperature resistance, as well as scratch resistance. They are particularly recommended for marking cables and wires used outside and in the defense industry. The labels consist of a descriptive field that contrasts well with the surface of the wire and a protective laminate that covers the descriptive field when applied to a round element. The protective laminate provides optimal protection for the marking against moisture, dirt, and mechanical damage. Other colors of descriptive fields are available upon request.
