What are the raw materials of TTO high-speed coding carbon belt?

TTO (thermal transfer coding) high-speed coding carbon tape raw materials mainly include the following parts:

1. Ink layer

Core material: The ink layer is the core part of the TTO carbon belt, which is responsible for printing and determining the use characteristics of the carbon belt, such as chemical corrosion resistance and anti-friction. The ink layer is usually made of mixed base, advanced mixed base or resin based ink, which can transfer the corresponding text, bar code, picture and other information to the soft film or label under the heat and pressure of the print head of the TTO coding machine.

2. PET membrane

Carrier material: PET (polyethylene terephthalate) film as the carrier of other layers, has an important impact on the heat conduction performance, directly determines the printing effect. PET film not only has excellent physical properties, such as high strength, high transparency, etc., but also has good chemical stability and thermal stability, which is very suitable as the base material of TTO carbon belt.

3. Back coating

Special coating: The back coating is an important part of the TTO carbon strip, and its main role is to reduce the wear of the print head, reduce static electricity generation and enhance heat conduction. This special coating usually contains lubricants or other additives to protect the print head while improving printing efficiency. The quality of the back coating directly affects the service life and print quality of the carbon strip.

4. Other auxiliary materials

In the production process, some other auxiliary materials may also be used, such as adhesives, isolation paper, etc. Although these materials are not directly involved in the printing process, they have an important impact on the manufacturing, storage and use of carbon strips.

In summary, the main raw materials for TTO high-speed coding carbon strips include ink layers (mixed base, advanced mixed base or resin-based inks), PET films (as carrier materials), and back coatings (special coatings containing lubricants or other additives). The selection and quality of these raw materials directly affect the printing effect, service life and cost effectiveness of the TTO carbon belt. With the continuous progress of technology and the increase of application demand, the raw materials of TTO carbon belt are also constantly innovating and developing.
