The aluminum closure has become the `hallmark’ for good and consistent quality across a wide range of bottled products.

All over the world, aluminum closures are widely recognised by industry experts, producers, retailers and consumers for their ability to preserve the genuine flavour of the precious contents inside the bottle.

Aluminum's inherent strength and corrosion resistance guarantees no change in taste

All materials used in aluminum closures are perfectly neutral from an organoleptic point of view, helping to preserve the flavours

The aroma and flavour are the same, whether opened 10 miles from the producer or 10,000

Aluminum closures create a highly effective barrier preventing contamination from micro-organisms, moisture or gas allowing a steady shelf life and safe storage

No cork taint or foreign bodies caused by traditional closure disintegration interferes with the precious liquids either!

Red or white or rosé; still or sparkling – today wine is enjoyed by many. Indeed each year it is estimated that 34 billion bottles of every quality, taste and price and for every kind of occasion are consumed around the world.

Different strengths, flavours and varieties are now available across the world thanks to modern production methods and packaging. Previously much wine was famous – or more accurately infamous – for not ‘travelling well’. Today a huge variety of wine is produced in many different countries and, thanks to technologies such as aluminum closures, is enjoyed globally. The aroma and flavour are the same, whether opened at the vineyard or on the other side of the globe.

Even when the wine is supposed to ‘breathe’ a little after opening, a good closure ensures the consistency of its flavour until it is opened. Too much oxygen in the bottle is something to be avoided; exposure to air can result in the wine eventually ‘turning’.

Brand owners and producers strive to differentiate themselves from the competition and to create a ‘personality’ as well as a reputation for their products, with which consumers can identify. With so many varieties and brands produced worldwide each year it is not surprising that, in addition to flavour and aroma, the visual impression, the style of the bottle, label and its closure is of such importance.

For producers and marketers, aluminum closures have the potential to enhance the brand appearance of their products. Intricate design options include glossy or matt finishes, embossing and even digital printing are readily available.

There are few technical or practical limits when it comes to giving aluminum closures an individual touch. These can augment the visual experience and enhance the overall impression. Just as the label makes a statement about the product – its origin, heritage and quality – so can the aluminium closure become a major part of its branding and visual impact.

Closures made of aluminium offer a number of clear advantages, as they can be manufactured in large numbers in a cost-efficient way, to produce an excellent price/performance ratio. Depending on their design, they can be significantly lower in price than traditional closure systems.

Aluminum closures are manufactured all over the world and are part of the local value chain. This allows a faster reaction to the customer’s needs. They can be transported economically and sustainably to the producer, whatever the location.

Aluminum closures are the only form of closure suitable for both glass and PET bottles. Single serve PET bottles with aluminium closures are lighter and therefore reduce transportation costs making them ideal for use on airlines and trains and at outdoor events. They also meet possible safety requirements of, for example, airlines, bars, concerts, sporting events and festivals when necessary.

The consumer can easily determine if the content has been tampered with as the bridge line on the cap will have been broken. Thanks to innovative technology different types of tamper evident devices can be included in the aluminium closures – a clear example of technology providing an economic advantage.

Aluminum closures only require a simple twist making opening a bottle easy and stress free eliminating any potential for annoyance. They are a guarantee of convenience, reliability and safety every time the bottle is opened and re-closed.

Add to this the convenience which comes from being able to store and transport a bottle with an aluminium closure in any position and over long distances, and it really demonstrates its claim to be the perfect closure.  

The aluminum closure's highly effective barrier properties prolongs, in perfect condition, the life of a product and is a reassurance to the consumer that the overall quality will remain at peak condition over a considerable period.
