Coating process of organic silicon high temperature double faced adhesive tape. The substrate is PI or PET film.
As long as you glue and coated gum to meet the requirements, Bieji coated silica gel. Apply the gel two days later.Basically coated silica gel will not be degumming.
My company has done this thing, remember it is not PET, PI is not sure.
PP forum, a lot of PET film information, there are many PET film and packaging printing friends
