Cap Seal or Bottle Seal is a sign that the bottle is new and has never been used. Most beverage products have a ring-shaped packaging seal or safety ring on the neck of the bottle. The ring secures the drink lid tightly, so it doesn't open easily.
The function of the ring seal on the cover of the packaged drink bottle is to indicate that the drink has not been opened and drunk by someone else. Apart from that, a tight seal also prevents and prevents drinks from being directly exposed to external conditions, thus giving rise to consumer confidence in the safety aspect of the product.
