Freezerbondz printable labels for thermal transfer printers. Freezerbondz labels can be applied to frozen surfaces including glass and polypropylene stored in liquid nitrogen. They have good print smudge resistance, solvent resistance, and good high and low temperature performance. Freezerbondz labels perform well in common laboratory environments such as liquid nitrogen and autoclave applications. For tube/vial applications these labels must be wrapped upon itself with at least 1/8 inch overlap. These labels are on a 1" core, a 'smaller core' than the majority of our materials. The recommended printer for these small core parts is the BBP11-34L printer. *Freezerbondz is a trademark of Brady Worldwide, Inc.
