Unprinted labels are used for printing variable information, such as contact details and/or warehouse and logistic data. They are divided into: thermal-transfer printing labels and direct thermal printing labels.

Thermal-transfer printing labels (TTR)

They are used for printing variable data such as barcodes, production date, expiry date, etc. The printing is done by means of thermal transfer ribbons (TTR), using the following types of printers: ZEBRA, CAB, CITIZEN, SATO etc.

The most frequently used materials include:

  • semi-gloss paper – coated paper, used to enhance the visual quality of a label by adding a glossy finish to it
  • vellum paper – used to achieve a dulling effect, for instance on bio product labels
  • polypropylene (PP) or polyethylene (PE) films – resistant to weather, humidity
  • PET films – able to withstand higher processing temperatures

The most frequently used materials include:

  • thermal top-coated paper – paper coated with varnish which protects it from dampness and fats
  • thermal eco paper – uncoated paper used for the production of labels which are unexposed to dampness and staining
