What is the substrate of BOPP color thermal sensitive synthetic paper?

The substrate of BOPP color thermosensitive synthetic paper is biaxially oriented polypropylene (BOPP) film. This type of film is made by adding various additives to polypropylene resin through processes such as mixing, melting, extrusion, blowing, stretching, heat setting, cooling, trimming, and winding. BOPP film has the advantages of light weight, high transparency, good mechanical properties, good dimensional stability, and high surface glossiness, making it an ideal substrate for manufacturing BOPP color thermal sensitive synthetic paper.

In BOPP colored thermosensitive synthetic paper, BOPP film serves as the carrier layer, coated with colored thermosensitive material containing a thermosensitive agent. When the thermal print head applies heat to the paper, the thermal agent undergoes a chemical reaction, resulting in a color change and the formation of colored images or text on the paper. Therefore, the quality and performance of BOPP film have a significant impact on the printing effect and service life of BOPP color thermosensitive synthetic paper.
