What are the material compositions of colored thermosensitive synthetic paper?

The material composition of colored thermosensitive synthetic paper mainly includes the following parts:

1. Substrate:

Color thermal sensitive synthetic paper usually uses BOPP (biaxially oriented polypropylene) film as the substrate. BOPP film has excellent physical and mechanical properties, such as tensile strength, tear strength, rigidity, and transparency, making it an ideal choice for making thermal paper.

2. Thermal sensitive coating:

Thermal sensitive coating is a key component of colored thermal sensitive synthetic paper, which determines the printing effect and color performance of the paper. Thermal sensitive coatings typically contain various chemical substances such as thermal dyes, colorants, sensitizers, stabilizers, etc.

In colored thermosensitive synthetic paper, thermosensitive coatings contain dyes of different colors to achieve color printing. These dyes undergo chemical reactions when heated, combining with the color developer to form visible images or text.

3. Protective layer:

In order to protect the thermosensitive coating from external environmental damage, colored thermosensitive synthetic paper usually adds a protective layer above the thermosensitive coating. This protective layer can be waterproof, oil resistant, wear-resistant, and extend the storage time of printed content.

4. Other additives:

In addition to the main components mentioned above, colored thermosensitive synthetic paper may also contain some other additives to improve its performance or meet specific usage needs. For example, anti-static agents can be added to improve the anti-static performance of paper, or lubricants can be added to reduce friction and noise during printing.

In summary, the material composition of colored thermosensitive synthetic paper is relatively complex, requiring precise proportioning and fine processing of multiple chemicals to produce. The selection and ratio of these materials have a significant impact on the printing effect, durability, and environmental friendliness of colored thermal sensitive synthetic paper.
