Frequently Asked Questions

Q1: Are your direct thermal labels BPA/BPS-free and phenol-free? +

A: DT Eco is BPA-free. DT Top-coated grades are produced without bisphenol chemistry, so they are BPA-, BPS-, and phenol-free. If you need phenol-free media, choose Top-coated DT (data sheets available on request).

Q2: Will these work with my printer? +

A: Yes — 102 × 76 mm labels are suitable for most desktop and industrial thermal printers from Zebra, TSC, Citizen and Toshiba. Choose 25 mm / 38 mm cores for desktop, or 76 mm for industrial printers.

Q3: Are 102 x 76 mm labels waterproof? +

A: Direct Thermal paper isn’t waterproof. For moisture, abrasion or chemical exposure, select Thermal Transfer synthetics (polypropylene or polyester) with a wax-resin or resin ribbon.

Q4: Which adhesive should I choose for freezers or temporary use? +

A: Choose Freezer-grade permanent for chilled or frozen goods, and Removable for short-term applications or reusable trays.
Compatibility: Freezer adhesive is offered with Top-coated DT and TT Paper; Removable is not available with TT Polyester or Tamper-evident materials.

Q5: Do you offer this label in other sizes? +

A: Yes — we also produce 101.6 × 76.2 mm (4×3″), 102 × 152 mm (4×6″), and 100 × 100 mm (4×4″) labels, plus custom sizes to order.
