solid Foil hot stamping

In recent years, with the improvement of stamping materials and stamping plate processing level, as well as the use of new machinery and equipment, the domestic stamping technology has also obtained some new development.High-speed bronzing, three-dimensional bronzing, holographic positioning bronzing and reprinting after bronzing have been widely used in the production of cigarette packages.Folded solid bronzingThree-dimensional bronzing: three-dimensional bronzing technology is a combination of bronzing technology and embossing technology, is the use of corrosion or engraving technology will be bronzing and embossing graphics and text into a up and down match with the negative die gravure and male die relief, bronzing and embossing technology to achieve a complete process.This process simultaneously completes the bronzing and the pressing concave and convex, reduces the processing procedure and the overprinter may not produce the waste product, enhances the production efficiency and the product quality.Because the product effect formed by three-dimensional bronzing is embossed three-dimensional pattern, can not be printed on it, so it must use the first printing and then hot process design, at the same time because of its high precision and high quality requirements, is not suitable for the production of cold stamping technology.There are usually two kinds of stereoscopic bronzing equipment, which is not suitable for stereoscopic bronzing.Rotary stamping method is usually used in web processing.Because the circular pressure is line contact, can completely avoid the possible bubble phenomenon in flat stamping, at the same time, fast speed, good quality.But because its stamping and bottom die relief are round, difficult processing, high cost, circular stamping heat transfer effect is not very ideal, so it is not widely used, often in some large production, high quality long version live, such as cigarette, wine, health products, etc.Due to the popular soft packaging of high-grade cigarettes, the original application of mature post-press processing technology on white card paper, has also been transferred to soft paper.Soft paper embossing, positioning stamping this process will be bronzing, embossing in a process to complete, the product has a full bronzing, fine text and text, beautiful, no embossing askew . characteristics.But this technology is very difficult, hot stamping plate, holographic film, hot stamping machine precision requirements are particularly high, all operating indicators are very strict.Also because of this, it is difficult to imitate, anti - counterfeiting degree.
