Blue4est®Sustainable Technology for Thermal Printing Paper
Thermal paper free of chemical color developers that releases images from a purely physical process. This product consists of three layers: a base paper, a colored paper, and an opaque paper layer. The opaque layer is comprised of polymeric particles (opaque styrene acrylic resin hollow spheres) that hide the pigmented-colored layer. When the opaque layer is exposed to heat, it becomes transparent, creating the print by revealing the colored layer underneath.
