Thermoplastic waterproof labels are specifically designed to permanently adhere to vials, microtubes, microplates, glass tubes, freezer boxes, polycarbonate cryo boxes, and other containers that will undergo long-term deep-freeze or cryogenic storage in liquid or vapor phase liquid nitrogen, laboratory freezers, as well as transportation on dry ice. Resistant to multiple freeze-thaw cycles without fading, detaching, or wrinkling, these laser labels are provided in sheet format for printing with desktop and office laser printers, are wear-and-tear proof, will not jam printers, and resist UV and gamma irradiation.
