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 — 101.6 × 152.4 mm is the exact 4×6″ shipping label size supported by most couriers and printer setups. Choose the correct core for your printer: 19 mm (portable), 25 mm / 38 mm (desktop — e.g. Zebra GK420D / ZD421), or 76 mm (industrial — e.g. Zebra ZT series).

Q3: Are 101.6 x 152.4 mm labels waterproof? +

A: Direct Thermal paper isn’t waterproof. For long-life or outdoor applications, select Thermal Transfer synthetics such as polypropylene or polyester, printed with a wax-resin or resin ribbon.

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

A: Use Freezer-grade permanent for chilled or frozen goods, and Removable for short-term or repositionable labels (e.g. retail).
Compatibility: Freezer is offered with Top-coated DT and TT Paper; Removable is not available with TT Polyester or Tamper-evident materials.

Q5: Do you offer other sizes or formats? +

A: Yes — we manufacture a wide range of thermal printer label sizes, including 76 × 38 mm, 100 × 100 mm and 100 × 150 mm. We can also produce custom sizes to your exact dimensions.

Q6: How do I know what type of label I need? +

A: Tell us about your printer, environment and application in the enquiry form — we’ll recommend the best print method, material and adhesive for your use case.
