What is the transparency of BOPP colored thermosensitive synthetic paper?

The transparency of BOPP colored thermosensitive synthetic paper is very high.

BOPP (biaxially oriented polypropylene) film itself has a significant characteristic of high transparency, which enables BOPP colored thermal sensitive synthetic paper to clearly display the background of images or text on its transparent substrate before being subjected to thermal reactions. In addition, BOPP films prepared by biaxial stretching process are stretched in two vertical directions (longitudinal and transverse) to rearrange the molecular chains of the film and form highly oriented structures, further improving the transparency of the film.

Therefore, BOPP color thermosensitive synthetic paper can present more vivid and vivid color effects when printing anti-counterfeiting labels or performing other printing tasks, while maintaining a high degree of transparency, making the printed content clearer and easier to identify.
