Cloth gold foil paper


The main sources of cloth gold foil paper are domestic and imported. import
Gold foil paper has high performance requirements and the price is naturally high. In recent years, with the popularity of domestic fabric bronzing, the quality of domestic bronzing papers has also been continuously improved. In addition, the low-cost, easy-to-operate properties of fabric gold foil paper also add a lot of added value to the fabric. Cloth bronzing brings huge business opportunities to Chinese bronzing foil merchants. China's Yangtze River Delta and the Pearl River Delta are huge consumers of bronzing foils. For example, Handan Philippine provides these customers with professional, high-quality, and suitable bronzing materials with convenient and thoughtful services. The color and variety of bronzing papers for fabrics are very diverse. Big choice space. Cloth gold foil paper needs to be used as a medium.
Structure editing
The structure of hot stamping paper is divided into: base layer, peeling layer, color layer, plating layer, glue layer.
The first layer: the base layer generally used 12μm-25μm thick biaxially stretched polyester film, the main role is to support the coating attached to it, to facilitate the continuous hot stamping process. It has properties such as tensile resistance and transient high temperature resistance.
Second layer: The release layer is generally coated with a silicone resin or the like. The main function is to enable the pigment, aluminum, and adhesive layers to quickly separate from the polyester film after hot stamping and be transferred and bonded on the surface of the stamped object. The peeling layer should have good peeling performance, otherwise it will make the hot stamping graphic blurry, and the dew showering will affect the product quality of the hot stamping.
The third layer: color layer The main components are film forming, heat resistance, transparency, suitable synthetic resins and dyes. Commonly used resins include polyurethane nitrocellulose, melamine formaldehyde resin, modified rosin fat and the like. During production, the resin and dye are dissolved in an organic solvent to form a color paste, which is then coated and dried. There are two main functions: one is to display the color; the other is to protect the aluminum plated image that is stamped on the surface of the article and is not oxidized. Electrochemical aluminum foil colors are golden, orange, gray, red, blue, green and so on. The color of the color layer is given a luster through the aluminum plating layer, and the color has a certain change. For example, the color of the yellow layer is gold after plating, and the gray color is gray after aluminum plating. The application of the color layer is delicate without any small particles, so as to avoid trachoma, uniform coating.
The fourth layer: plating layer will be coated with a thin film, placed in a vacuum continuous aluminum plating machine vacuum chamber, under a certain degree of vacuum, through resistance heating, the aluminum wire melting and continuous evaporation to the film layer, An aluminum layer was formed. The main function of the aluminized layer is to reflect light, change the color of the color layer, and make it appear metallic.
Fifth layer: The glue layer is generally a fusing thermoplastic resin. According to the material to be stamped, different resins may be used. The resin may be dissolved in an organic solvent or formed into an aqueous solution and coated on the aluminum layer by a coater. After being dried, it is a glue layer and its main function is to bond the hot stamping material to the hot object. During hot stamping, one of the main reasons for the phenomenon of unsatisfactory hot-stamping is that the glue layer is not matched, and the type of galvanized aluminum foil used for different stamping objects should be different.
