Professional Laminated Label

Brother’s TZe laminated tapes consist of six layers of materials, resulting in a thin and extremely strong label. Characters can be formed using thermal transfer ink that is sandwiched between two protective layers of PET (polyethylene film), which protect the text against the effects of liquids, abrasion, temperature, chemicals, and sunlight.
