3M Office Tapes

The vinyl surface accepts most permanent markers reasonably well, allowing you to add text or codes to colored tape sections. Ballpoint pen doesn't write as reliably on vinyl surfaces. For best results with written additions, use fine-point permanent markers and allow a moment for ink to set before handling. If extensive written information is needed, consider using the colored tape as a category indicator alongside separate written labels rather than trying to fit detailed text on the tape itself.

Apply tape to clean, dry surfaces free from dust and oils. Press tape firmly across its entire length, paying particular attention to edges where peeling typically starts. For file folder tabs, wrap tape around the tab edge rather than ending exactly at the edge where handling naturally catches tape ends. Avoid applying tape over existing labels, coatings, or textured surfaces that prevent good adhesive contact. If tape won't stay on specific folders, the folder surface may be incompatible; test different folder brands or consider folders designed for tab labeling.

Width selection depends on visibility requirements and available application space. The 9mm (approximately 3/8 inch) narrow width works for small items, tight spaces, and applications where subtle marking is acceptable. The 12mm (approximately 1/2 inch) standard width provides good visibility for most file, cable, and general marking applications. The 24mm (approximately 1 inch) wide width creates bold, highly visible marking for warehouse applications, large equipment, and situations where identification must be visible from a distance. Choose the narrowest width that provides adequate visibility for your application.

Calculate based on tape length per roll (66 meters/216 feet for Scotch 690) and tape usage per item. A typical file folder tab application uses approximately 2-3 inches of tape. At 2.5 inches per file, one 66-meter roll marks approximately 1,000 files. Estimate your file count per color category and add 10-20% margin for waste and errors. For ongoing systems, track actual consumption to refine ordering quantities. Buying in bulk quantities typically reduces per-roll cost for large implementations.

Scotch 690 colors (red, blue, yellow, white) provide clear visual distinction under standard office lighting including fluorescent. These primary colors are chosen specifically for easy differentiation. Problems arise when systems attempt to distinguish too many similar colors (light blue versus medium blue, for example). Stick with distinctly different colors that remain distinguishable even in varying light conditions or to workers with color vision differences. For accessibility, consider combining color with position or pattern differences so color isn't the only distinguishing factor.
