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.
Handle in accordance with good industrial hygiene and safety practice. Use personal protective equipment as required.
