PET protective film is also known as film high temperature resistant polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields. It can produce cell phone LCD protection film, LCD TV protection film, cell phone keypad, etc.

What are the applications of PET film

Common PET film applications are: photoelectric industry, electronic industry, wire and cable industry, . Hardware industry, 5. Printing industry, plastic industry, etc.

In terms of economic benefits, such as good transparency, low haze and high gloss. It is mainly used for high-grade vacuum aluminized products, which are mirror-like after aluminizing and have good packaging and decoration effects; it can also be used for laser anti-counterfeiting base film, etc. High gloss BOPET film has large market capacity, high added value and obvious economic benefits.

Laser cutting is the most widely used laser processing technology. The principle is that the laser is focused and then irradiated on the material, causing the temperature of the material to rise until it melts or vaporizes. With the relative movement of the laser and the material, a cutting slit is formed on the cut material, thus achieving the purpose of cutting.

 Advantages of PET film process

The advantages of laser cutting are mainly as follows.

1. high cutting accuracy, narrow cutting seam, good quality, small heat-affected zone, and flat and smooth cutting end face;

2. fast cutting speed and high processing efficiency;

3. non-contact processing, no deformation, no processing chips, oil, noise and other problems, is a green processing;

4. Strong cutting ability, can cut almost any material.
