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

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

DTP Films are commonly used in airline baggage tags, food labels, and barcode applications. These films are valued for their water, oil, and handling resistance. However, what sets Cosmo Direct Thermal Printable (DTP) Films apart is their unique protective layer, delivering a paper-like matte finish with dark printing. 

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 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.

Where are DTP films required?

From 2018 to 2022, the DTP film’s sales witnessed significant growth, registering a CAGR of 3.4%. The global demand for these films is projected to increase at a CAGR of 4.1% during the forecast period. DTP films are used in varied applications such as:

  • Airline baggage tags
  • Ready-made food labels
  • Industrial bar code applications
  • Retail price marking
  • Courier industry labels
  • Fruits & Meat labels

Some of the latest industries where DTP is being used include:

  • Healthcare: Prescription labels, patient identification tags, and medical device instructions.
  • E-commerce: Shipping labels and return tags for enhanced efficiency in parcel management.
  • Event Management: Wristbands, badges, and tickets with dynamic printing capabilities.
  • Hospitality: Custom labels for inventory tracking and patient bands.

Why are DTP Films preferred over traditional methods?

DTP films are water, oil and plasticizer resistant, and in addition to that, they also offer an outstanding paper like matte finish which in the end produces a fine, sharp dark image on printing.

Direct Thermal Printing is slowly gaining ground and is being extensively used for indoor use. This is fundamentally because of its extreme ease of use while being cost-effective, as it does not require a ribbon to print the image. 

Direct thermal labels are extremely easy to use as the printer just needs to place the label stock into the printer and print. Thus, there are no additional high equipment costs and even the maintenance and troubleshooting/fixing costs are almost non-existent.

Further, the sensitive data is always imaged directly onto the BOPP DTP film, thus protecting the privacy and primacy of sensitive information.

Moreover, there is no requirement of additional inventory items such as ribbons, ink or toners, and the companies just need to order the label stocks needed for their initiatives. This makes the complete ordering and use process much simpler and streamlined, and also reduces the warehouse requirements.
