300DPI TTO Thermal Transfer Printer

Thermal Transfer Overprinters (TTO) use flat product films as their core printing medium. Their precise adhesion and long-lasting clarity make them crucial in multiple industries that rely on film packaging.

In the food industry, TTO is primarily used for various flat food packaging films. Examples include aluminum-plastic composite films for puffed foods, PE fresh-keeping films for frozen foods, and transparent OPP films for baked snacks. TTO can efficiently print information such as production dates, best-before dates, and batch codes on these flat surfaces. The printed labels are resistant to grease and low temperatures, remaining legible even in refrigerated environments and after contact with food oils and fats, avoiding blurring caused by film wrinkles or friction, and strictly meeting food packaging hygiene and traceability requirements.

In the pharmaceutical packaging sector, TTO is used to print critical information such as batch numbers, expiration dates, and traceability QR codes onto flat substrates such as pharmaceutical aluminum foil composite films and PVC/PVDC composite films for capsule packaging. These films have smooth surfaces and require extremely high marking precision. TTO (Telescopic Tolerance) technology enables high-definition printing on micron-level flat films, ensuring burr-free text and barcodes. This technology meets the pharmaceutical industry's stringent packaging labeling standards and facilitates full lifecycle traceability of pharmaceuticals.

The daily chemical industry also relies on TTO for flat film packaging. For example, TTO can print expiration dates, ingredient codes, and production batch numbers on BOPP film labels attached to composite tubes for shampoo and shower gel, or on PE packaging films for laundry detergent. The printed information adheres tightly to the film surface and resists fading or peeling, even in humid environments or with frequent handling, ensuring both practical and aesthetically pleasing product labeling.

Furthermore, in film packaging for small electronic components, such as anti-static PE film bags for resistors and capacitors, TTO can precisely print component model numbers, specifications, and other information on the flat film surface, providing clear labeling support for warehouse management and quality traceability. Its directional adaptability to flat films makes it a key device for efficient and reliable labeling of film-based packaging products.
