The bronzing foil looks like a thin film. In fact, it consists of a thin base film of PV or PE, a release layer, a colored layer, a steamed layer (thick adhesive layer), and then five layers of materials. In fact, there are many varieties of bronzing foils to match the same hot materials, such as PP film or polished paper products, metallic inks, cloth, PVC glue, hot line stripes or large physical objects and printed materials. To select the bronzing foil of the same material to match.
The main technologies of vacuum evaporation bronzing film include vacuum evaporation, coating, and chemical ingredients, especially the chemical ingredients are the key factors that affect the finished product. The core technology of general bronzing film production is precision coating and chemical formulation. The production process is described as follows: First, the original film of PET (polyethylene terephthalate) and OPP (extended polypropylene) is used as the material, which will be formulated The resin and solvent are colored and coated on the original film, and then a layer of metal film is attached by vacuum evaporation, followed by a glue coating process, and then slit or rolled foil.
