Abstract

A process prepares a polymer-coated hard shell capsule, suitable as container for pharmaceutical or nutraceutical biologically active ingredients. The hard shell capsule can include a body and a cap. In the closed state, the cap overlaps the body either in a pre-locked state or in a final-locked state. The hard shell capsule can be provided in the pre-locked state and spray-coated with a coating solution, suspension, or dispersion that includes a polymer or a mixture of polymers to create a coating layer which covers the outer surface of the hard shell capsule in the pre-locked state.
