The main components of BOPP thermal sensitive synthetic paper include the following parts:


1、 Base material

Biaxially oriented polypropylene (BOPP) film: This is the substrate of BOPP thermal synthetic paper, which provides the main structure and strength of the paper. BOPP film has high tensile strength, impact strength, rigidity, and toughness, making it an ideal material for producing thermal sensitive synthetic paper.

2、 Thermal sensitive coating

Thermistor: Thermistor is a key component in thermosensitive coatings, typically present in the form of microcapsules or dyes. When thermal paper is heated, the thermal agent will undergo a chemical reaction, resulting in color changes and the formation of images or text.

Other additives: In order to improve the performance and stability of the thermosensitive coating, some other additives such as lubricants, antioxidants, etc. may also be added.

3、 Functional fillers and additives

Pigments and dyes: Depending on the needs, pigments or dyes can be added to give BOPP thermosensitive synthetic paper specific colors.

Antioxidants: Used to improve the antioxidant properties of paper and extend its service life.

Fluorescent whitening agent: used to enhance the whiteness and brightness of paper, and improve the printing effect.

Titanium dioxide: a commonly used white pigment that can enhance the whiteness and opacity of paper.

4、 Application of new materials

With the development of technology, some new materials have also been applied in the production of BOPP thermal sensitive synthetic paper, such as:

High molecular weight polypropylene: can significantly improve the tensile strength, impact strength, and toughness of paper.

Modified polypropylene: By adding an appropriate amount of modifier, the processing performance of polypropylene and the physical properties of the final product can be improved.

Bio based additives: Additives made from bio based raw materials can reduce dependence on fossil resources and lower carbon emissions during the production process.

Zero halogen flame retardant: used to improve the environmental performance and safety of products.

Waterproof and oil resistant coating: It can significantly improve the water resistance and oil resistance of BOPP thermal synthetic paper.

Antibacterial coating: used to inhibit the growth and reproduction of microorganisms such as bacteria and molds, and improve the hygiene performance of products.


In summary, the main components of BOPP thermosensitive synthetic paper include BOPP film substrate, thermosensitive coating (containing thermosensitive agents and other additives), functional fillers and additives, and the application of new materials. These components together constitute the special properties and wide application scenarios of BOPP thermosensitive synthetic paper.
