The incisions are always cut out and have burrs. What is the reason?
I don't know what kind of slitting blade you're using. We also make plastic film products.
Well, you leave your phone with me, and I'll send you the information about our cooperation manufacturer! Go and see for yourself! Their quality is quite good! I hope I can help you!
I've had this kind of problem before. Now redesign, replace the blade, cut it much better! You might as well try it!
