Direct Thermal Printable (DTP) Films – What are they and why do we need them?

If your business or work ever dealt with airline baggage tags or food labels and barcode applications, you must have come across the term ​DTP films​, and might be confused as to what they are and why exactly do we need them. What are Direct Thermal Printable (DTP) Films? DTP films are ​BOPP based films​ with a proprietary coating which enables the formation of an image or impression on the films upon contact with the heated print head of a thermal printer. A protective layer is generally applied to protect the coated surface from mechanical abrasion, damage due to climatic factors or chemical products etc. Direct thermal printing is generally used for tagging and labeling applications where elaborate printing is not required and printing is done only for critical information like barcodes. In direct thermal printable film, heat is used to print the image. This printing technology uses a matrix which contains “ink” in a colourless form as a coating on the surface. The application of heat from the print head of the thermal printer activates the ink to develop colour and the image is formed. Drying of coating is very critical and normally takes place at low temperature to avoid the pre-image formation.
