Brother's unique, patented TZ tapes are designed to be extra hard wearing. Brother laminated tapes consist of six layers of materials, resulting in a thin yet extremely strong label. Characters formed with thermal transfer ink are actually printed onto the underside of the laminate. Sandwiched between two layers of PET (polyester film) this lets you create characters that are virtually indestructible. Brother TZ tapes are available in various widths (6,9,12,18,24,36mm).
