Hi, I have a film that is a laminate of metallized Polyethylene Thereftalate(mPET) + 50 microns Polyethylene(PE).
I want to kiss-cut the PE in order to peel it off. However the PE stays almost unaffected by the CO2 (30W, 10.6 micron wavelength) laser whilst the underlying mPET gets cut. This is the opposite of the behavior I need.

I'm not really expert. Any workaround? Thanks
