Chemical Resistant Labels

Understanding the chemical-resistance capabilities of labels will help keep your samples and laboratory safe and organised. These labels have been categorised into 4 tables based on printing format (thermal transfer, direct thermal, laser printer and write-on) and include the details of their chemical resistance when the selected printed format is used.

A label selection and printing guide is also available.

Thermal Transfer Printing

Thermal transfer printers provide printing to withstand harsh environments, ideal for applications requiring chemical resistance. See printers here.

Direct Thermal Printing

Direct thermal printers use rolls of labels coated with a leuco dye which changes colour when heat is applied. See printers here.

Laser Printing

Laser desktop printers use toner cartridges to produce a smudge-proof, waterproof, UV-resistant, and cryogenic-resistant printout with various colours. See Label sheet templates for MS Word.
