Duratherm labels and tags are easy to use and do not require a ribbon to print. Ideal for indoor labeling applications where temperatures do not exceed 140 °F (60 °C). Duratherm III IR is a top-coated paper label that provides sharp text and barcode printing. This material can be scanned with either a visible light or infrared scanning device. Duratherm III IR is recommended for use in direct thermal applications where surface contamination is a concern for barcode scanning (e.g., healthcare).
