Spray film formulations for can bodies
Inside coatings for beer and beverage cans are designed to be applied in a 1- or 2-coat system in thin and low film weight. Spray film formulations for can bodies contain different additives or agents for different purposes. For example lubricants, scratch resistance, anti- foaming and more. There is no standard coating for inside cans.
The formula and coating system is made to match not only the food or beverage content but also technical requirements of production (for example the sterilization process) and EU or US or global and local requirements.
