What are the applications and advantages of PET protective film after laser cutting?

PET protective film is also called 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 mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc.

Common PET film applications include: optoelectronic industry, electronics industry, wire and cable industry, hardware industry, 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-end vacuum aluminum-plated products. After aluminum plating, it is mirror-like and has good packaging decoration effect; it can also be used for laser anti-counterfeiting base film, etc. The market capacity of high-gloss BOPET film is large, the added value is high, and the economic benefits are obvious.

PET laser die cutting is the most widely used laser processing technology. The principle is that the laser is focused and irradiated on the material, so that the temperature of the material rises to melting or gasification. With the relative movement of the laser and the material, a cutting seam is formed on the cutting material, thereby achieving the purpose of cutting.

The advantages of laser die cutting machine are mainly manifested in:

1. High cutting accuracy, narrow cutting seam, good quality, small heat-affected zone, and smooth cutting end surface;

2. Fast cutting speed and high processing efficiency;

3. It is a non-contact processing, without deformation, processing chips, oil pollution, noise and other problems, and is a green and environmentally friendly processing;

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