Self-adhesive printer labels Brady M4-49-422, polyester, 25.4×25.4 mm, black on white, 260 pcs

Brady M4-49-422 self-adhesive printer labels are polyester, gloss-finish labels with black print on a white background, sized 25.4 × 25.4 mm. The single-roll pack contains 260 durable labels designed for thermal transfer printing and general identification tasks including asset tagging, cable marking and component labeling. The B-422 polyester material is halogen-free and formulated to resist abrasion, solvents and a wide temperature range, enabling long-term identification in industrial and commercial environments.

Advantages

The polyester construction delivers strong mechanical resistance to scratching and scuffing while remaining compatible with thermal transfer ribbons for sharp, legible print. A permanent acrylic adhesive provides reliable bonding to a variety of surfaces, including rough, smooth and powder-coated flat substrates. The material is engineered to withstand common solvents such as alcohol and oil and to operate across elevated and reduced temperatures. Certified to relevant industry standards, these labels are suitable when durable, machine-printed identification is required.

Suitable for

• Asset tagging and inventory labels
• Cable and wire marking in control panels and installations
• Component and PCB identification
• Barcode labels for scanners and handheld readers
• Equipment and safety marking in industrial settings

How to use

Load the roll into a compatible Brady handheld or desktop thermal transfer printer following the printer manufacturer’s instructions for label roll installation. Select a thermal transfer ribbon matched to polyester media for optimal print durability and contrast. Design the layout (text, barcodes or symbols) in the printer software, confirm print settings for label size 25.4 × 25.4 mm, and run a test print. After printing, apply labels to clean, dry, and oil-free surfaces, pressing firmly to ensure full adhesive contact.

Usage recommendations

For best long-term performance, clean the application surface with a suitable solvent that does not leave residues (for example isopropyl alcohol), allow it to dry, and avoid applying labels to curved or highly textured surfaces where full adhesive contact cannot be achieved. Use a compatible thermal transfer ribbon designed for polyester films to ensure abrasion and solvent resistance of printed information.
