Why do bottles have freshness seal or a safety ring?

There are clearly defined regulations for bottling mineral water. In order to make sure that the original purity of the water remains intact, natural mineral water must be bottled directly at its source and in packaging intended for the consumer. The bottle cap must be designed in such a way that you, the consumer, can easily identify whether or not, the bottle still has its original seal. So all our aluminium caps have a freshness seal and the plastic caps have a security ring.
