What is the effect of laser cutting machine cutting PET film? Will cutting PVC edges turn black and yellow? How to deal with it? Today, Redsail Laser will introduce the processing technology of PET laser cutting machine to cut plastic film.


In recent days, several customers who asked me to make samples are cutting PET, PVC and other films. If you cut PET and PI with our CO2 CO2 laser cutter, the edges are perfectly fine, no yellowing or burnt. For example, some customers not only cut a layer of film, but also cut a layer of double-sided tape together. We can add an air compressor and increase the blow so the edges don't turn yellow.


The following pictures are all PET films, all of which are cut with a 60W40X60cm table top model. The edges can be said to be very clean, and there is no browning at all. If only one layer of film is cut, to reduce reflections caused by the bottom plate, replace the blade plate, or cut a layer of paper directly underneath.

For the laser cutting of PVC materials, the edges are basically unavoidable from yellowing. I tried to emphasize the light just enough to cut through, and increase the blowing air to the maximum. Even the laser tube was replaced with an imported RF laser, and the focusing mirror was also replaced with Even with the lens with the smallest focal length, there will still be yellowing in the end.


The above is the introduction of the PET laser cutting machine plastic film cutting process. There are many plastic components, in addition to PET, PVC, PI, PP, PS, ABS and so on. The actual cutting effect of the material should be subject to the actual proofing test
