Site of Manufacture (and Product Code)
Michem® Flex Barrier 5780 is designed to be applied onto AlOx coatings produced on Bobst supplied vacuum platforms on BOPET substrates. A thin, dried coating is transparent, contributes to AlOx protection and allows further processing of BOPET/AlOX film. Properly coated and dried films are not expected to exhibit blocking to the backside. Suggested coat weight is 0.4 – 0.8 dry gsm. It should be diluted to 15-20% solids with soft water and dried thoroughly after application. If needed to adjust coat weight and processability, it is possible to dilute further with soft water.
