Thermaltransfer Ribbon

Consists of a 4,5 µ strong polyester foil, which on side is covered with a minimum of one 2 - 4 µ strong layer, sensitive to heat, and on the other side with a back-coating.

Different contingents of wax, artificial resin, colour pigments (for black: grim particles) and additives give the thermal transfer colour its attributes:

• Transferability (dependent on composition, melting point and viscosity)
• Printability and adhesion on different kind of materials
• Resistance of the printout against mechanical and chemical influence, heat and UV radiation
• Optical thickness

Further coatings can come to the own layer, such as

• Release layer (eases the dissolution of the layer) and
• Top-coat (specifies the connection of the layer with the labelling material). The very thin backside coating on a silicon base has to accomplish 3 prerequisites
• Burn-out protection of the polyester foil
• Decrease of electrostatic charge
• Improves sliding attribute
