wrapping (also wrappings ) = paper or paper-like material that is put round something: 'I wanted to tear off the wrapping and see what was inside.'
packaging = the container or material that something is placed in by a manufacturer, especially to protect it or make it look attractive: 'Packaging should be biodegradable and kept to a minimum.'
Note that both wrapping and packaging are used in connection with food: 'Somewhere on the packaging/wrapping there should be a date stamp.'
