Our High Temperature Labels are used for identification of high-heat items like circuit boards and related electronic components, where a soldering flux or wave soldering process is used or if the product will be exposed to a chemical cleaning cycle. Backed with a pressure-sensitive acrylic adhesive, these labels have excellent barcode readability after chemical and high-temp exposure.
