Frequently Asked Questions
Q: What type of printer do I need for these 4x6 direct thermal labels?
A: You need a direct thermal label printer compatible with 4x6" (100x150mm) labels — such as popular desktop models from brands like Zebra, DYMO, Rollo, or Munbyn. No ink cartridges or ribbons are required; the heat from the print head activates the thermal coating to produce the print.
Q: Are these labels compatible with Amazon FBA shipping requirements?
A: Yes! These labels meet the standard 4x6" size specification required by Amazon FBA, as well as most major carriers including USPS, UPS, FedEx, and DHL. They are ideal for printing Amazon FBA shipment labels, packing slips, and carrier shipping labels.
Q: Will the labels hold up in wet or humid conditions during shipping?
A: Absolutely. These thermal labels feature a water and grease-resistant coating that keeps printed barcodes, addresses, and tracking numbers sharp and scannable even when exposed to moisture, condensation, or light oily surfaces during transit and warehouse handling.
Q: What is the difference between the 100-label and 500-label packs?
A: Both packs contain the same high-quality 4x6" direct thermal labels in a stacked (fan-fold) format. The 100-label pack is great for light shipping or trying the product, while the 500-label pack offers a better value per label for businesses with higher shipping volumes.
