What are the main raw materials used to produce BOPP thermal synthetic paper?

The main raw materials for the production of BOPP thermal synthetic paper include the following parts:

1. Base Material

The substrate is the support layer of the thermal sensitive synthetic paper. For the BOPP thermal sensitive synthetic paper, the substrate is mainly composed of biaxially stretched polypropylene (BOPP) film. BOPP film has the characteristics of high strength, high gas resistance, good printing performance and tear resistance, is the largest consumption of PP film products, widely used. BOPP film is made of polypropylene resin by a bidirectional stretching process, with good flexibility and smoothness, which ensures smooth transfer of paper and provides a stable printing surface.

2. Thermal Sensitive Material

Thermal sensitive material is the key part of thermal synthetic paper printing. It contains thermogenic chemicals that, when stimulated by heat, change color to form an image or text. This thermal agent is usually a microcapsule or dye, and its choice depends on the specific needs of the printing. These materials are coated on a BOPP substrate, allowing the heat-sensitive synthetic paper to display the desired image or text information when heated.

3. Functional Additives

During the production process, in order to improve the performance of BOPP thermal synthetic paper, some functional additives may also be added. These additives include but are not limited to antistatic agents, smoothing agents, stiffening agents, anti-reflection agents, pearling masterbatch, whitening masterbatch, anti-adhesion masterbatch, etc. The addition of these additives can significantly improve the antistatic properties, surface smoothness, rigidity, transparency, whiteness and anti-adhesion properties of thermal sensitive synthetic paper, so as to meet the needs of different application scenarios.

In summary, the main raw materials for the production of BOPP thermal synthetic paper include BOPP film as a substrate, thermal agent as a heat sensitive material, and various functional additives that may be added. The selection and matching of these raw materials is critical to the performance and quality of the final product.
