1What is metal hot stamping film?

People who have contact with printing must be familiar with hot stamping film. Hot stamping film can generally be used on a variety of products, such as product packaging, greeting cards, cosmetics, household appliances, automotive interior and exterior decoration, etc. Hot stamping film can be divided into many types according to its properties, among which metal hot stamping film is more special. Today we will learn about metal hot stamping film in detail.

Metal hot stamping film, also known as aluminized film, is a hot stamping material made by vacuum evaporating a layer of metal on a film base. It can generally be divided into 5 conventional process flows, and its production process is as follows:

2 Base film layer
The base film layer is also called the base layer or carrier, which supports other layers. Its thickness can be divided into 12 wires, 16 wires, 18 wires, 20 wires, and 25 wires. Generally, a 20-wire thick PET film is often used. This type of PET film is resistant to high temperatures and can reach up to 170°C. It also has good unidirectional stretchability and is not easy to break when stretched.

3 Release layer
It is referred to as release layer. This layer can quickly separate the ink, aluminum layer and glue layer from the PET plastic film during hot stamping, so as to quickly transfer and bond to the surface of the substrate.

4 Ink layer
This layer provides a variety of color effects, protects the ink and aluminum layer at the same time, and can enhance the brightness of the hot stamping paper after hot stamping. It is mainly composed of a variety of synthetic resins and dyes to form colorful colors, such as red, green, yellow, blue, purple...

5 Metal layer
The metal layer is also called the aluminum layer. It is formed by vacuum high-temperature evaporation, cooling, sublimation and precipitation of metal. The post-printing effect has a metallic feel, which improves the grade of the product.

6 Glue layer
It is mainly composed of hot-melt plastic or resin. Its function is to bond the aluminum layer and ink layer to the surface of the substrate under the action of pressure and temperature.
