Brady M4-1-425-FP P‑Form Flag Labels, polypropylene white matt, 29.97 × 20.02 mm, permanent adhesive, 120 labels

Brady M4-1-425-FP P-form flag labels are white matt polypropylene self-adhesive flags sized 29.97 × 20.02 mm supplied as a roll of 120 permanent-adhesive flags. Intended for cable marking, wire routing and component identification, these flags combine a durable polypropylene face with a permanent adhesive suitable for long-lasting indoor applications. The matt white surface provides a printable area compatible with common thermal transfer and laser printers used for labelling small cables and parts.

Advantages

The polypropylene construction offers resistance to moisture, light mechanical abrasion and common indoor pollutants, extending the life of printed information. The matt white finish reduces glare and improves contrast for printed text and barcodes. Permanent adhesive provides reliable fixation on smooth and slightly textured surfaces such as cable jackets, wiring looms and plastic housings, while the compact flag shape is designed for clear identification without obscuring surrounding components.

Suitable for

• Cable and wire identification in electrical panels and control cabinets
• Labeling small components and harnesses in assembly and maintenance
• Creating compact, printable flags for wire routing and terminal marking

When it may not be suitable

These flags are intended for indoor use and may not perform as reliably in prolonged outdoor exposure to UV, extreme temperatures or continuous immersion. They are not designed for surfaces with heavy oily residues or contaminated, highly textured surfaces where permanent adhesive may fail.

Key specifications

• Material: polypropylene, matt white face
• Label dimensions: 29.97 × 20.02 mm
• Adhesive type: permanent pressure-sensitive adhesive
• Quantity: 120 labels per roll
• Recommended applications: cable marking, component identification, wire routing

How to use

Print the required text, numbers or barcodes using a compatible thermal transfer or laser printer and appropriate ribbon or toner settings for polypropylene media. Clean the target surface to remove dust, oil or moisture, then apply the flag label firmly, smoothing from the center outward to ensure adhesion. Position the flag so the printable area is visible and does not interfere with connectors or moving parts. Allow a short dwell time after application for the adhesive to develop full bond strength.

What to consider before purchase

• Compatibility with your label printer and print method (thermal transfer or laser)
• Suitability of permanent adhesive for the intended substrate (cable jacket, plastic, painted metal)
• Indoor use preference; limited outdoor/chemical exposure resistance
• Required label size and printable area for your text or barcode

Usage recommendations

For best results use cleaned, dry surfaces and test print settings on a single label before full production runs. For installations exposed to higher temperatures or chemicals, consider testing adhesion and print durability under expected conditions or select a material specifically rated for those environments.
