A core focus area in the field of Coating resins is Can Coatings. Food and beverage cans preserve the taste and nutritional values of their filling for up to several years. As a consequence of such long storage times, the interactions between the packaging and the food need to be minimized. Cans are typically coated with an organic layer that protects the integrity of the can from effects of the food and prevents chemical reactions between the can’s metal and the food. To fulfill the technical and legal requirements, (1) can coatings should withstand the production and sterilization processes , (2) be universally applicable for all food and beverage types , (3) prevent chemical migration into food in quantities that endanger human health , (4) adhere to the can even after unintentional deformation , (5) resist aggressive food types and protect the metal of the cans , (6) and preserve the food and maintain its organoleptic properties over several years.

Epoxy-based coatings have the highest market share of more than 90%. However, manufacturers and food companies have started to replace epoxy coatings with alternatives as a consequence of toxicological evidence, public discussions, and recent regulatory decisions. Acrylic and polyester coatings are currently used as first generation alternatives to epoxy coatings.
