The film coating process is generally performed after the tablet has been formed and any desired active ingredients have been added. The film coating material is applied in a controlled environment in order to ensure that the correct amount of material is applied and that the resulting coating is of uniform thickness.

Once the film coating has been applied, it needs to be cured in order to form a strong bond with the tablet surface. This curing process usually involves exposing the coated tablets to heat or ultraviolet light.
