PET membrane is also known as high-temperature polyester film, which has excellent heat, cold, oil, and chemical resistance. Its function can be divided into PET high-gloss bright membrane, chemical coating film, PET anti-static membrane, PET thermal seal film, PET thermal contraction film, aluminum plating PET film, etc. It has excellent physical properties, chemical performance and size stability, transparency, and recyclability. It can be widely used in magnetic records, sensitivity materials, electronics, electrical insulation, industrial film, packaging and decoration, and other fields. Can produce mobile phone LCD protective films, LCD TV protective films, mobile phone keys, etc.
Typical PET membrane applications include the photoelectric industry, electronics industry, wire and cable industry, hardware industry, printing industry, plastic industry, etc. In terms of economic benefits, such as good transparency, low mist, and high gloss. It is mainly used for high -end vacuum -plated products. After aluminum plating, it is a mirror, and the packaging decoration effect is good; it can also be used for laser anti-counterfeit base membrane. The highlight BOPET film has a large capacity, high added value, and obvious economic benefits.
The laser currently used in PET film cutting is mainly a nanosecond solid ultraviolet. The wavelength is generally 355nm. Compared with 1064nm infrared and 532nm green light, 355nm ultraviolet energy has a higher single-light point. The material absorption rate is higher. It has a more minor impact and achieves higher processing accuracy. The edge of the cutting is more flat and cleansing, and there are no burrs and miscellaneous edges after amplification.
The advantages of laser cutting are mainly manifested:
1. High cutting accuracy, narrow seams, good quality, cold processing, small heat affecting zone, cutting end surface is smooth and smooth;
2. Fast cutting speed, high processing efficiency, improvement of production efficiency;
3. Adopt precision interactive workbench, configure automation/manual working mode, and fine processing;
4. The quality of the beam is high, which can achieve ultra-fine labeling;
5. It belongs to non-contact processing, no deformation, no processing debris, oil pollution, noise, and other problems, which is a green environmental protection processing;
6. Strong cutting capacity, you can cut almost any material;
7. Fully closed safety rack to protect the safety of operators;
8. The machine operation is simple, with no consumables and low power consumption.
