 All interior-use coatings are U.S. Food and Drug Administration (FDA) compliant. Formulations are available that are epoxy-free, as well as BADGE-compliant and NOGE free for European can makers.
For three-piece steel food can bodies, epoxy-phenolic and organosol interior coatings are available in clear, gold, zinc oxide and aluminized. Also available is a new white coating with excellent chemical and stain resistance. Side-stripe coatings afford superior protection and coverage of the seam, and work in concert with the interior body coating.
For two-piece steel cans, aluminized, gold and zinc side interior coatings are available in epoxy-phenolic for shallow-draw and organosols and polyesters for deep-draw.
For two-piece drawn-wall-ironed cans, PPG also offers a choice of water- or solvent-based internal coatings in gold, white or aluminized gray. |
Exterior base coats and varnishes complete the food packaging coatings line, and are designed for process compatibility with PPG's interior food can body coatings. Base coats for two-piece cans are available in clear and gold-tone.
For the European market, PPG supplies exterior decorative inks. New two-coat systems comprising the white base coat and inks for tin-free steel can bodies eliminate the need for the clear over varnish, simplifying processing and reducing costs while achieving the level of protection and aesthetics of three-coat systems. Side-stripe coatings for interior and exterior application are especially resilient. |
