Top-coated thermal substrates are direct thermal labels with a protective coating designed to prevent contamination of the thermally-printed image from any condensation, fats, grease, solvents and plasticisers from packaging films that the labelled product may come into contact with during transportation and storage. Top-coated grades are usually found in supermarkets on fresh and frozen products. They are principally selected for pre-packed meat and cheese that requires individual description and barcode.
