Lacquer coating for aluminium packaging is vital because it protects the quality and the integrity of contents in the packaging. BS EN 15421 specifies test methods to determine the adhesion of this coating. These test methods will help you to identify how the lacquering performs under vertical and horizontal compressions. These test methods help you to determine product packaging quality and enhance product shelf life.
