Features of cake packaging bronzing
In recent years, with the improvement of people's requirements for the appearance and quality of commodity packaging, printing technology and cake packaging technology have made great progress, and post-press processing technology has achieved vigorous development. As part of the processing, the changes in the past few years are even greater. The continuous emergence of new technologies, new processes and the combination of various technologies has made the packaging printed matter achieve good results in terms of gloss, three-dimensional, metallic and anti-counterfeiting performance after hot stamping. A wide range of three-dimensional hot stamping technology makes the packaging of goods look high-end, exquisite, magnificent and full of personality. At present, this technology is mainly used in greeting cards, bookmarks, trademarks, tobacco and alcohol packaging and various high-end packaging boxes. Three-dimensional hot stamping equipment Three-dimensional hot stamping equipment usually has two types: flat pressing and round pressing. Round pressing is not suitable for three-dimensional hot stamping. The flat pressing and three-dimensional hot stamping equipment is represented by the Swiss BOBST equipment, which is developing in the direction of high speed, high precision and convenient use, and is the main type of three-dimensional hot stamping. BOBST hot stamping machine has reached a hot stamping speed of 7500 sheets/hour, and the accuracy can be kept within 0.1mm. It is one of the most advanced hot stamping machines in the world. The round stamping method is usually used for in-line processing of webs. Since the round pressing is a line contact, the bubble phenomenon that may exist in the flat pressing can be completely avoided, and the speed is fast and the quality is good. However, because the bronzing plate and the bottom mold relief plate are round, the processing is difficult and the cost is high. Versions, such as cigarette packs, wine packs, health care products, etc. Both bronzing and embossing technology are traditional post-press processing technologies, which are indispensable processes in packaging and decoration. Now the two are used together, which not only reduces the production process, but also improves the production efficiency. The decoration effect and anti-counterfeiting function have been greatly improved.
