Our freezer-grade blackout labels will completely obscure any existing label and cover-up the information underneath. Designed for storage in low-temperature freezers (-80°C), or transportation on dry ice, these labels are perfect for re-labeling vials, tubes, and freezer boxes when removal of the existing labels is not possible. Printable with all common thermal-transfer printers, these deep-freeze labels are also suitable for use at room temperature and in high-heat conditions, able to resist temperatures up to +120°C.
