Thermalmark Labels


  • Thin, durable construction materials make it easy to use in most desktop thermal transfer printers.
  • Thermal transfer receptive topcoat allows for easy on-site label customization and printing.
  • Durable .002” polyester material easily conforms to uneven or radius surfaces
  • .001" thick adhesive provides excellent adhesion to low and high surface energy materials.

Metalcraft's Thermalmark Polyester Labels offer the durability of a pre-printed label with the flexibility to custom print information on-site as needed. The thermal transfer receptive topcoat of the Thermalmark allows labels to be easily customized with different text, barcodes, or serial numbers printed through a thermal transfer printer.
