Compatible P-touch label tape

This 10-pack of GREENCYCLE MK-421 tape works with Brother P-touch label makers including PT-45M, PT-55BM, PT-65, PT-70, PT-80, PT-85, PT-90, PT-M95, PT-100 and PT-110 models. Each cartridge holds a 9mm by 26.2ft roll of non-laminated tape. The tape prints black text on a red background for colour-coded organisation.

Indoor organisation use

The tape suits home and office labelling of shelves, file folders, storage boxes, USB sticks and food containers. Its adhesive resists water, grease, temperature changes and UV exposure without peeling or cracking. Buyers needing laminated tape for outdoor or heavy-abrasion environments should look elsewhere.

9mm width compatibility

The single specification that decides fit is the 9mm tape width, which matches the MK-421 / M-K421 / M421 cartridge format required by the listed P-touch printers. Using a different width cartridge will prevent the label maker from operating correctly.

Questions about this item

What width tape does the MK-421 cartridge use?

The cartridge holds 9 mm (0.35 inch) wide tape, matching the Brother M421 specification.

How do I load the cassette into my PT-90 label maker?

Open the cover, drop the cassette in with the tape facing down, close the cover, then press the feed key once to advance the tape past the split-back liner.

When should I replace the tape cassette?

Replace the cassette when the 26.2 ft (8 m) roll runs out or if the adhesive stops sticking cleanly to surfaces.
