Aluminium Collapsible Tube Inks & Coatings

Collapsible tubes are manufactured by extruding slugs of aluminium. These along with similarly manufactured rigid aluminium containers for pharmaceuticals and aerosols cans are printed by rotary presses after forming. Ink plays an important part in the overall performance of the decorative system. They are printed either directly on to the metal substrate, or over a transparent size or pigmented enamel. The ink must possess excellent adhesion and flexibility characteristics.
