Manufacturer printed customized gold and silver hot laser metal wire drawing high-end packaging plastic bag

Bronzing and silver stamping process uses the principle of hot press transfer to transfer the aluminum layer in electrolytic aluminum to the surface of the substrate to form a special metal effect.

Since the main material used for bronzing and silver stamping is electrochemical aluminum foil, bronzing and silver stamping is also called electrochemical aluminum hot stamping. Electrochemical aluminum foil is usually composed of multi-layer materials, and the base material is usually polyethylene, followed by separation coating, color coating, metal coating (aluminizing) and glue coating.

In the printing industry, electrochemical aluminum foil is often printed on paper, which is called hot stamping. Hot stamping is a general technical term. Bronzing doesn't mean it's gold. There are many kinds of gold-plated paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.

Application of bronzing and silver stamping process:

1. Ordinary gold, laser gold hot stamping. It can be used for hot stamping of gold cards, silver cards, laser cards, glass cards and most other products.

2. Positioning holographic bronzing. Holographic laser positioning electrochemical aluminum is a special process application in design. It has corresponding anti-counterfeiting patterns, which can greatly improve the anti-counterfeiting ability of products and improve the grade of products. This kind of electrolytic aluminum is generally produced in China. Compared with foreign imports, the price is cheap, but the stamping performance is slightly poor.

Holographic laser positioning electrochemical aluminum has a great relationship with the control of stamping temperature, stamping pressure and speed, and even the stamping model.

Bronzing, also known as "hot stamping". A printing process. Emboss golden words or patterns on printed matter. Silver stamping, silver stamping and gold stamping are similar, but the materials are different. From the appearance, silver stamping presents silver luster; Bronzing presents golden luster.

Note: both gilding and silver stamping belong to the printing process, which is characterized by clear and beautiful patterns, bright colors, wear resistance and weather resistance. Bronzing technology is mainly used in prepress process, and the scope of hot stamping is still expanding.

Since the quality, specification and model of electrochemical aluminum foil will affect the hot stamping quality, the reasonable selection of electrochemical aluminum foil is the prerequisite to improve the quality of hot stamping process.

To choose electrochemical aluminum foil correctly, we must understand its composition and hot stamping mechanism. The bronzing effect mainly depends on the temperature, pressure and bronzing speed, which cooperate with each other to make products.

If you want to control the stamping quality, you should master the reasonable stamping temperature, stamping pressure and stamping speed, so that the stamping quality can be guaranteed.

Bronzing process is a complex process technology. In the process of album hot stamping, only by grasping these problems can we obtain satisfactory hot stamping effect.

Bronzing has two main functions:

First, surface decoration can improve the added value of products. The combination of bronzing and other processing methods such as embossing can better show the strong decorative effect of the product.

The second is to give products higher anti-counterfeiting performance, such as using holographic positioning hot stamping trademark logo.

After bronzing, the product has clear and beautiful patterns, bright colors, wear resistance and weather resistance. The application of bronzing process on printed cigarette labels accounts for more than 85%. In graphic design, bronzing can make the finishing point and highlight the design theme, especially suitable for the decorative use of trademarks and registered names.
