Blue/White/Pink/Black Hot Stamping Foil for Paper

Hot stamping foil uses PET as a based foil, coating with release layer, color layer, aluminum layer and adhesive layer. The polyester carrier, PET, is the supporter for other coating. Upon application of heater &/or pressure, release layer allows other layers to release from the PET carrier to the surface of substrate. Lacquer or color coat has two functions: carriers the color tint in the form of pigments or dye, and protects aluminum layer on the substrate so that it will not be oxidized. The forth layer, aluminum layer provides the reflective qualities and opacity desired in metallic foils. Adhesive coat serves to bond the foil to the substrate being stamped. This determines the printability on different substrates. In other words, we choose different adhesive coatings according to substrate material.
