Printer label Brady M21-250-C-342-YL — Yellow non-adhesive polyolefine, 11.1 mm × 2.1 m

Brady M21-250-C-342-YL is a yellow non-adhesive printer label made from heat-shrink polyolefin designed for wire and component marking. With a printable width of 11.1 mm and a continuous length of 2.1 m, the label material provides a durable, heat-shrinkable sleeve suitable for temporary or semi-permanent identification where adhesion is not desired. The polyolefin construction offers resistance to abrasion, solvents and environmental factors after heat shrinking, delivering legible printed text and a compact fit around cables and small components.

Advantages

The material combines heat-shrink performance with a bright yellow color for high visibility and clear contrast for printed text. Non-adhesive construction eliminates residue concerns and simplifies removal or repositioning when needed. The continuous roll format and compatible printer support efficient, on-demand printing of multiple labels of varying lengths. The sleeve’s compatibility with thermal transfer printing ensures sharp, durable markings appropriate for electrical, industrial and telecom environments.

Suitable for

• Cable identification and wire marking
• Temporary tagging of components and harnesses
• Identification in electrical panels and junction boxes
• Marking in industrial and telecom installations

How to use

Select the Brady-compatible label printer and set the printer to the correct media type for heat-shrink polyolefin. Design and print the required text or graphics using thermal transfer-compatible ribbon and the appropriate print settings for clarity. Slide the non-adhesive sleeve onto the wire or place it over the component before applying heat. Use a heat gun or approved shrinking tool to evenly apply heat until the sleeve conforms snugly to the substrate and the print becomes legible and secure.

Usage recommendations

For best results, verify printer settings and ribbon compatibility before printing, and perform heat shrinking in a controlled manner to avoid overheating. Allow labels to cool and inspect adhesion and legibility after shrinking. Store unused rolls in a cool, dry place away from direct sunlight to preserve material properties.
