Bronzing Technical Data

With the improvement of the national economy and the development of the printing and packaging industry, people require the packaging of products: exquisite, environmentally friendly, and personalized. In the post-press processing of packaging products, the hot stamping process is loved by people because of its unique surface finishing effect, and is used in the packaging of banknotes, cigarette labels, medicines, cosmetics and so on. Hot stamping has two main functions, one is surface decoration to improve the added value of the product. Love festive, resplendent and resplendent for our national tradition, bronzing and embossing process combined to show its luxury; The second is to give the product a higher anti-counterfeiting performance, using holographic positioning hot stamping trademark logo, anti-counterfeiting. At the same time, bronzing is very able to show the personalization of product packaging and safety and environmental protection. Therefore, many packaging are used in the hot stamping process.

1. Bronzing principle: After a certain temperature and pressure, the color foil instantly attaches the pattern and text of the plate to the plastic surface.

2, bronzing conditions: 1, temperature 2, air pressure 3, color foil 4, bronzing version

3, bronzing version:

High quality bronzing version is the primary factor to ensure the quality of bronzing. At present, the production of hot stamping plate mainly uses photographic corrosion process and electronic engraving technology, materials commonly used copper plate or zinc plate. The copper plate is made of fine material, and the surface smoothness and heat transfer effect are better than the zinc plate. The use of high-quality copper plate can improve the gloss and contour clarity of bronzing graphics and texts. The traditional photographic corrosion technology to produce hot stamping plate process is simple, low cost, mainly used for text, thick lines, general images. The hot stamping plate made by electric carving can show rich and delicate level changes, which greatly expands the packaging performance ability. The process is conducive to environmental protection, but the investment in electric carving equipment is large, and the depth of carving is not ideal at present, which is easy to cause hot stamping "paste plate". Holographic anti-counterfeiting hot stamping plate production technology requirements are higher, previously mainly in Taiwan or abroad production, plate-making cycle is longer, only for fixed, large-scale product packaging.
