First choice closure for spirits
The excellent open and reclose features of aluminium closures are also great advantages, locking in the flavour and ensuring there is no leakage. In addition technical features can be incorporated into aluminium closures, such as tamper-evident devices and anti-counterfeiting or authentication systems. These can protect not only the valuable contents but also brand integrity.
Indeed, the first aluminium rolled-on pilfer proof (ROPP) closure, was introduced in the spirits market where it continues to be the closure of choice. ROPP still accounts for nearly 70% of all aluminium closures used with alcoholic beverages.
