A Comparison of Aqueous Primers for Anchoring Vacuum Deposited Aluminum to Film Substrates

Presented by Ginger Cushing, Michelman Inc

This study presents three water based coatings which were applied to treated film substrates and subsequently vacuum metalized with aluminum. The primers produced strong adhesion between metal and film. Oxygen transmission rate tests show promising barrier performance. This technology would be suitable for packaging and protecting low moisture contents such as snacks, biscuits and powders.
