Description Low-Temperature Labels for Thermal-Transfer Printers Size: 0.9375″ x 0.9375″ / 23.8mm x 23.8mm Available colors: White Label across: 1 Core: 1″ or 3″ available Labels/roll: 1,000 Adhesive: Max strength extra-permanent Perforation: Yes Temperature range:  From -196°C to 110°C Our thermal-transfer cryo labels resist extreme low-temperatures, including temperatures as low as liquid nitrogen (-196°C /-321°F), making them perfect for labeling air and fuel cooling systems as well as cryoelectronics. Coated with a permanent adhesive, our cryogenic barcode labels adhere to wet and damp surfaces and withstand spraying and rubbing with alcohols and sanitizing wipes. These low-temperature labels can be printed on with all common thermal-transfer printers to incorporate serialized information and high-quality barcodes. Benefits: Resistant to extreme cryogenic conditions, including liquid nitrogen (-196°C/-321°F) Strong permanent adhesion, even to wet surfaces, with excellent grip on curved surfaces These labels are resistant to spraying and swabbing with alcohols RECOMMENDED RIBBONS Smudge and Alcohol Proof Resin Ribbons: RR-CLASS
