It is normal to not know the main materials of heat transfer film. of. In fact, according to the structure of the heat transfer film, there are heat transfer film base film, release agent, ink, adhesive and other materials. Let's take a closer look together next!
Adhesive
The adhesive for heat transfer is a hot melt adhesive, which is a colorless, transparent or light yellow viscous liquid. After drying and forming a film, the film is transparent. It has excellent composite fastness and excellent composite fastness on the surface with the release agent and ink. It has good flexibility, abrasion resistance, water resistance, acid and alkali resistance, and good wear resistance.
Ink
Thermal transfer inks are gravure inks, and the drying of the ink mainly depends on the volatilization of the solvent. After the substrate film is determined, the appropriate ink should be... less
