Acid and Alkali Resistant Label

The Acid and Alkali Resistant Label is a specialized industrial marking solution engineered for environments where standard labels fail. Its facestock is a chemical-resistant polyester film, paired with a chemical-resistant permanent adhesive to ensure secure bonding on challenging surfaces. This construction is designed specifically for thermal transfer printing, and for optimal durability it should be paired with a chemical-resistant resin ribbon. While the temperature range and thickness options are not fixed, they are confirmed based on the selected construction, ensuring the final product matches your operational demands precisely.

Performance is where this label truly excels, offering robust resistance to a broad spectrum of corrosive agents. It withstands exposure to strong acids and alkalis, including hydrofluoric acid (HF), sulfuric acid (H2SO4), and sodium hydroxide (NaOH), as well as aggressive solvents like xylene, toluene, acetone, alcohol, and methyl ethyl ketone (MEK). The label also resists degradation from commercial cleaners, surface disinfectants, industrial flux, oil grease, degreasers, paint strippers, and gasoline. Notably, it maintains barcode readability even after immersion testing and remains adherent in seawater for at least 90 days, providing long-term reliability in the harshest conditions.

These labels are ideal for identifying chemical drums, process tanks, industrial pipes, and equipment, including containers exposed to aircraft cleaning chemicals or pest and weed control mixtures. They also suit automotive engine compartments where solvent and fluid resistance is critical. Because certification support depends on the selected variant and application, please confirm your specific requirements with our team before ordering. With 19 years of label production experience, we know which material suits which job.
