Unfired ceramic barcode label. This barcode label is fused onto the product during the heat treatment process of the production line.

Labels can be printed on-site by regular thermal transfer barcode printers with special ink ribbons.

When fused onto glass, metal, or ceramic, they transform into longlasting ceramic barcode labels that resist heat and chemical.

Chemical resistance

  • Good.
  • GL-450 labels may be treated for chemical processing as described below, before firing. After the label is fired, the barcode can be read.
    NaOH (8%, 20°C, 30sec.) > HF (8%, 20°C, 30sec.) > NH4F (5.5%, 20°C, 30sec.) >Fired


Material Unfired ceramic
Thickness 0.03 to 0.12 mm
Mounting Temporary fixation with back side adhesives, then fused to the material after firing.
Barcode All kinds of barcodes including 2D codes
PCS More than 75%
