Compatible Label Tape

Brother TC21 cassettes deliver red text on white laminated tape for PT-series labelers including PT-6, PT-8, PT-10, PT-12, PT-12N, PT-15, PT-20, PT-25, PT-150 and PT-170K. Each cartridge prints 12 mm wide labels on a 7.7 m roll. The two-pack suits offices, warehouses and retail counters that need colour-coded identification.

Indoor and Outdoor Durability

Laminated construction resists water, grease and grime so printed labels stay legible in hot, cold or damp conditions. Standard adhesive bonds reliably to flat surfaces such as paper, file folders and binders without special surface preparation. No power or cooling considerations apply to the consumable itself.

Drop-In Cartridge Format

Cassettes install directly into the listed PT models without tools or firmware updates. The 0.50 inch width fits the printer’s existing tape path and the 25.2 ft length reduces change-over frequency. Users who need different colours, widths or adhesive types must select alternative Brother tape cassettes.

Questions about this item

How do I insert the TC21 cassette into a PT-12 labeler, and what step is often missed?

Open the cover, drop the cassette in with the tape facing down, then close the cover until it clicks — the click is the step people skip, leaving the tape loose.

What part of the TC21 tape will need replacing first with regular use?

The 7.7 m roll inside each cassette runs out; when the red-on-white laminated tape is exhausted you simply swap in a new cassette.

What limits how long a printed TC21 label stays legible outdoors?

The standard adhesive and lamination resist water, grease, grime, heat and cold, so the first limit is the tape roll length of 25.2 ft per cassette.
