Hello!
Does anyone know how to get rid of silicone watermarks on PET sheet rolls. This is thin gauge RPET or PET. My material supplier says the watermark does not exist until the sheet is rolled up, but if the sheet stays flat the watermarks don't show up. We see the marks on the sheet and on the parts after thermoforming. I attached a picture showing the marks in question. Any insight would be appreciated.
