Premium Packaging-Bronzing

The hot stamping process uses the principle of hot press transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Because the main material used for hot stamping is anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping.

In the printing industry, hot stamping of electrochemical aluminum foil on paper is commonly used, which is called hot stamping. Hot stamping is a general term for a process. Bronzing does not mean that what gets hot is golden. There are many kinds of bronzing paper materials, including golden, silver, laser gold, laser silver, black, red, green and so on.

1. Ordinary gold, laser gold hot stamping. It can be used for hot stamping on most products, including gold cards, silver cards, laser cards and glass cards, and its application is more common.

2. Positioning holographic hot stamping. Holographic laser positioning anodized aluminum is a special process application in design, with corresponding anti-counterfeiting patterns, which can greatly improve the anti-counterfeiting ability of the product, and at the same time improve the grade of the product. This kind of anodized aluminum is generally produced domestically. Compared with foreign imports, the price is relatively cheap, but the bronzing performance is slightly worse. Holographic laser positioning anodized aluminum has a great relationship with the bronzing temperature, bronzing pressure and vehicle speed, and even the bronzing model.

3. The special application of anodized aluminum in the process. Hot stamping and then printing is a new idea in the cigarette label design and printing industry. The application of this process has high requirements for anodized aluminum. In addition to achieving accurate bronzing position, smooth and bright surface, balanced and uniform pressure, no blistering, no paste, etc., special attention must be paid to the edge of the bronzing pattern not to have obvious pressure The hot stamping anodized aluminum should have good adhesion on the hot stamping surface, and there should be no obvious scratches and scratches. Everyone knows that the bronzing process is actually a process in which the paper is heated and compressed. For white cards and glass cards, special attention should be paid to the protection of semi-finished products, and various unfavorable factors of paper deformation should be minimized during the production process. This will greatly help the smooth progress of the hot stamping process and the improvement of the product qualification rate.

There are also many kinds of bronzing crafts. The most common propaganda posters, business cards, profit seals, couplets, advertising paper, flannel packaging, and high-end paper packaging can all be bronzed.
