Will laser cutting PET, PI, and PVC films turn yellow, burnt and burnt edges? How to solve it? Today, Mr Wur, an engineer from Chanxan, will give you a detailed description of the edge effects of these three materials with a laser cutting machine and some solutions.

Cut PET, PI, PVC and other films. If you use a Chanxan laser carbon dioxide laser cutting machine to cut PET and PI films, the edges will be completely fine. They will not yellow or burn. Like some customers, they will not only If we just cut a layer of film and glued a layer of double-sided adhesive tape together and cut it together, we can add an air compressor and increase the blowing so that the edges will not turn yellow. For example, the two pictures below are all PET films, which are all cut with our 60W CW6040. The edges can be said to be perfect, and there is not a bit of browning. If you want to reduce the laser reflection caused by the bottom plate when you only cut a layer of film, you can use a knife strip, or directly put a layer of paper and cut underneath.
