Site of Manufacture (and Product Code)
Michem® Flex Barrier 5770 is designed to be applied onto AlOx coatings produced on Bobst supplied vacuum platforms on BOPET substrates. A thin, dried coating is transparent and contributes to oxygen barrier and AlOx protection of BOPET/AlOX film. Properly coated and dried films are not expected to exhibit blocking to the backside. Suggested coat weight is 0.3 – 0.5 dry gsm. It should be used undiluted and dried thoroughly after application. If needed to adjust coat weight or processability, it is possible to dilute slightly with soft water.
