Non-adhesive printer label Brady M21-375-C-342-YL, polyolefin, yellow, 1.64 cm x 2.1 m

Brady M21-375-C-342-YL is a yellow non-adhesive printer label manufactured from polyolefin film and supplied as a continuous roll 1.64 cm wide and 2.1 m long. Designed as a heat-shrink sleeve, this product is intended for wire marking, cable identification and instances where a durable non-adhesive wrap or sleeve is required. The material offers good dimensional stability and resists abrasion and many common environmental influences when shrunk to fit conductors and cables.

Advantages

This polyolefin sleeve combines ease of printing with heat-shrink performance to provide permanent identification on wires and cables without adhesive. The yellow color gives high contrast for printed text, improving legibility of circuit and component labels. The continuous roll format supports efficient printing and cutting to length in compatible label printers, while the non-adhesive design allows the sleeve to form a tight, conformal fit after heat application for long-term durability.

Suitable for

• Marking and identifying individual wires and small cables
• Labeling harnesses, terminals and connection points
• Applications requiring a heat-shrink sleeve rather than adhesive tape
• Environments where abrasion resistance and clear printed contrast are needed

Key specifications

• Material: polyolefin (heat-shrinkable)
• Color: yellow for high-contrast printing
• Width: 1.64 cm
• Length (roll): 2.1 m
• Format: continuous roll suitable for compatible label printers
• Type: non-adhesive sleeve/wrap for heat-shrink application

How to use

Print the required text on the polyolefin sleeve using a compatible label printer and appropriate print settings for shrinkable material. Cut the sleeve to the desired length and slide it over the wire, cable, or component to be marked. Apply heat evenly with a heat gun or approved heat source until the sleeve shrinks and conforms tightly to the substrate. Allow the sleeve to cool to ensure a permanent fit and clear, legible printing.

Usage recommendations

Use printing ribbons and printer profiles recommended for heat-shrink polyolefin to achieve optimal print adhesion and durability. Apply heat progressively and avoid concentrated high-temperature exposure to prevent damage to underlying insulation or components.
