Printing on flexible packaging for hot food

A suitable technology for industrial packaging

During the packing of hot food products such as sauces and prepared foods, the heat spreads through the packaging film and is therefore able to break down, melt or erase the ink. This constraint is amplified by the high speed of certain packing lines which require the use of a quick-drying ink.

Thermal Transfer technology offers a high-performance print solution for high-quality marking.

  • Certain Thermal Transfer printers can be integrated within the production or packing line and are able to operate in hot and humid environments;
  • In keeping with the demands of high-throughput applications, printing is possible at a speed of up to 1 metre per second, whether in intermittent or continuous mode;
  • Thermal Transfer inks offer excellent adhesive qualities for all types of plastic packaging, even pre-printed.


Quality printing for durable information

Thermal Transfer printing is able to mark all types of logos, text and numbers with a good visual finish and a level of resistance suitable for the product's environment of production and of use. To avoid an expiry date or any food traceability information being rubbed off, a Thermal Transfer ink must be selected that is able to provide resistance against heat, steam, abrasion and handling.

inkanto ribbons for hot product packaging

For packaging used on hot products, the Resin inks AXR®600, AXR®800 and AXR®900 for near-edge printers are recommended. Thanks to the sharpness of the print, the information is perfectly legible while the strong adhesion of the ink to the surface of the packaging film prevents the ink from being dispersed due to heat and avoids print degradation.

inkanto ribbons enable producers to comply with European regulations (1935/2004/EC) and US FDA requirements.
