Brother PT-70 Label Tape
Your Brother PT-70 labeller uses genuine Brother M series label tape in 9mm and 12mm widths. This compact handheld labeller is suited to everyday home, school, and office identification, including file folders, storage containers, school supplies, and personal items. Standard 9mm M-K221 and 12mm M-K231 black-on-white tapes handle general organisation, while options like M-K531 blue tape or metallic M-821 gold tape allow for distinct colour coding. Consumables for this label printer have been available from Ink Depot since Jan 2012. Australian customers rate Ink Depot 4.8 on Google.
Tape Length and Replacement Planning
Brother M series label tape cassettes for the PT-70 are engineered for practical everyday use. Standard tape cassettes typically supply up to 8 metres of continuous tape per roll, allowing you to produce dozens of custom labels depending on your typed text length. Ordering single cassettes is ideal when trying a specialised colour, while multipacks and value bundles provide convenient replacements for high-use items like standard black-on-white tape.
Selecting the Right Tape Width and Colour
Matching the correct tape width to your task ensures labels remain legible and fit comfortably on labelled objects:
- 9mm Tape (e.g. M-K221, M-821): Well suited to narrower surfaces such as spine edges on thin folders, small plastic containers, toolboxes, and stationery.
- 12mm Tape (e.g. M-K231, M-K531, M931): Provides extra surface area for larger text or multi-line prints, making it the preferred choice for storage boxes, shelving, and prominent file labelling.
In addition to standard black text on white tape, choosing background colours like blue (M-K531), gold (M-821), or matte silver (M931) allows for easy visual categorisation across home and workplace files.
