Synthetic cups for wines, sparkling wines and liqueurs

A high performance closure

Crafted to perfection

Cups for wines, sparkling wines and liqueurs are fundamental supports not only to avoid the accidental spillage of product from the bottle, but also to preserve the aroma, freshness and organoleptic characteristics for as long as possible. Currently, more and more products made with synthetic materials are becoming popular, but how do you choose the ones that best suit your needs? Let’s find out together in this practical and useful guide!

The caps used to close the glass bottles intended to contain mineral water and soft drinks are made of aluminum and equipped with a mastic seal.


The particularity of the aluminum capsules for mineral water and soft drinks produced by Alplast srl is linked to the presence of important cuts, functional to the proper disposal of glass by consumers.

Technical characteristics and advantages of synthetic caps Synthetic caps are not made of silicone, but with thermoplastic hot-foamed polymers, often lubricated on the surface with silicone origin materials to facilitate the uncorking and the insertion in the bottle hese products undoubtedly have several strong points, namely: – they are sterile and therefore cannot be attacked by mold; – they are insulating and have the ability to preserve the organoleptic characteristics of the drink for a reasonable time; – last a long time; – can be uncorked without the use of a corkscrew, thus saving a lot of time; – ensure a uniform yield and do not alter in any way the taste of the drink; – avoid the much-hated cork taste of the wine. The aforementioned phenomenon is caused by Armillaria Mallea, a parasitic fungus that emits trichloroanisole (TCA), a chemical substance with a rather unpleasant taste; – there are no flows during the aging phases; – they are environmentally sustainable and recyclable; – being neutral, they ensure that the drink does not absorb any foreign smell.

Synthetic inner and outer caps

There are two macro types of caps, namely internal and external. The first are to be placed in the neck of the bottle, while the second are crown or screw: the latter are mostly used for effervescent products. Synthetic aids are good substitutes for traditional cork, as they help to reduce costs and ensure excellent quality standards for a reasonable period of time.

The origins of synthetic caps

Synthetic caps for wines, sparkling wines and spirits first appeared in Italy and France in the mid-1970s as an alternative to the cork version.
But to see their widespread expansion, it was necessary to wait twenty years, when, thanks to the evolution of technologies and the development of new materials, these closures were also used on high quality drinks.
Today, in addition to providing the benefits mentioned above, these aids can be produced in attractive designs that are ready to impress consumers.
The consumption of alcoholic beverages has in fact become a real moment of conviviality, in which the aesthetic part has also assumed an important role.

How to choose the right cap for every drink
Before using a particular cap, the following parameters should be taken into account:
– Type of drink: A specific cap is needed for each drink.
For example, if the wine is new, not too fine and ready to drink, a synthetic cap would be perfect;
– pressure of the wine: if it is a sparkling or semi-sparkling wine, it is better to opt for a screw cap, so that it can protect its effervescence and avoid the unpleasant effect of fizzing;
– the internal profile of the bottle: this is used to determine both the diameter and the length of the cap, as volumetric expansion of the drink could occur.
