Various lacquers have been developed for lining cans, especially for preventing food discoloration that could occur as a result of interactions between the food and the can.
Internal coating eliminates the food-metal interaction during storage while the external protects the can from abrasion and corrosion.
Three-piece food cans are made from lacquered tinsheets. The lacquer is roller-coated the sheet at a rate of 3000 – 5000 sheet per hour.
The cured lacquer shows a film thickness of 3-6 microns – in other words a very thin film.
It also aids in forming of cup and provides base for decoration.
