ALKOvin™ is a one-piece sealing liner from the Meyer Seals® family of pressure seals.
ALKOvin™ offers a perfect combination of closed-cell polyethylene foam and high-quality barrier films for protecting wine and preserving its aroma – guaranteeing the purity of taste!
With a complete and varied range of sealing liners for aluminium caps, Meyer Seals® can meet the most diverse requirements for wine storage and maturation processes.
Independent research in recent years has shown that the cork taint is so unpleasant for consumers and wine connoisseurs’ which is caused by the migration of the chemical compound trichloranisole (TCA) or tribromo anisole (TBA) from the corks into the wine. About 5% of wine bottles closed with corks exhibit cork taint, making their contents unpalatable to consumers. Meyer Seals® ALKOvin™ range does not release any aroma-impairing substances into the wine, ensuring a consistently high level of aroma protection. The aroma, a wine producer's individual signature, enjoys reliable, long-lasting protection with Meyer Seals® ALKOvin™.
Decades of experience and the use of materials from reliable, responsible suppliers allows Meyer Seals® to guarantee the high quality of our ALKOvin™ sealing liners. Strictly controlled processes enable Meyer Seals® to ensure consistent quality throughout the chain of production.
The closed-cell polyethylene foam core’s elasticity allows Meyer Seals® ALKOvin™ sealing liner to compensate for system tolerances between the cap and the bottle, significantly contributing to the prevention of leaks when there is minor damage to the aperture surface. The outstanding level of shape recovery in this family of sealing liners ensures reliable functionality and safety throughout the entire storage period.
It has been argued for many years that cork has the desirable property of allowing wine to “breathe”. However, the cork’s permeability to oxygen varies just as widely as its quality does. This means that the producer cannot rely on consistent, controlled oxygen ingress. The solution is ALKOvin™. The mechanical properties of the barrier films used ensures consistent sealing system performance over the long term.
The innovative ALKOvin™ active liner addresses a problem that regularly faces wine producers worldwide. Among wine professionals, the terms "reductive flavour" and "post bottling off-flavour" are used to describe a phenomenon regularly reported by experts. With this revolutionary liner, ALKOvin™ active eliminates reductive conditions (low oxygen) in the bottle preventing and eliminating the formation of volatile sulphur compounds. Undesirable sulphurous odours are unwelcome consequences for consumers and producers, and the resulting commercial losses are severe. With its active layer, ALKOvin™ active is a revolutionary new product that binds and deactivates these sulphur compounds, protecting the wine's precious aroma. ALKOvin™ active reduces oxygen ingress to zero and is free from chlorinated hydrocarbons (PVDC). A 4-year study by the highly regarded AWRI (Australian Wine Research Institute) confirms the effectiveness of the ALKOvin™ active liner (study available on request here).
ALKOvin™ active is supplied as a pre-cut disc.

ALKOvin™ Saranex® combines ALKOzell™ closed-cell polyethylene foam with the original Saranex® film, in use for decades and a favourite among winemakers. This protective lamination combines high-quality components with a sealing system offering the highest surface quality, long-term elasticity, and durable shape-recovery. ALKOvin™ Saranex® guarantees a controlled low level of oxygen ingress.
Combined with Meyer Seals® ALKOzell™ closed-cell foam, ALKOvin™ EVOH offers a sealing system with excellent protection against oxygen ingress. ALKOvin™ EVOH guarantees a controlled low level of oxygen transmission. This sealing liner is free from chlorinated hydrocarbons (PVDC).
ALKOvin™ tin offers the most effective barrier to oxygen ingress over long periods. The ALKOzell™ foam core is laminated with a tin/PVDC film. The soft film of tin positively forms around the bottle aperture. Thus, resulting in a sealing liner that reduces oxygen ingress to zero. Wine bottles sealed with ALKOvin™ tin provide excellent long-term aroma protection.

“Before we used the ALKOvin™ active liner, we struggled with reductive off-flavours year after year in wines sealed with tin-lined screw caps. After six to nine months in the bottle, the original fruity flavour disappeared, and the wines were very closed, inexpressive, and deteriorated from then on. As a result, we were looking for a solution to this problem.
The ALKOvin™ active sealing liner was used for the first time in 2019 when bottling our basic tier wines. Working with this liner was exceptionally smooth. We only had positive feedback regarding the tightness and the outlier rate – the liner was completely within the tolerance range. Furthermore, the SO2 content was extremely stable after 9 months. In terms of aroma and fruit preservation of our wines, we experienced a significant increase in quality in comparison to previous years. This was confirmed by comparative blind tastings among colleagues against the conventional tin liner. The ALKOvin™ active variants were consistently perceived by all tasters as cleaner by smell, fruitier and crispier, with significantly more structure on the palate.
Switching to the ALKOvin™ active sealing liner was a pioneering move and the right decision for us for the future.”
“I have been using ALKOvin™ active liners for more than two years now and I am very pleased and excited about the result. I hand-harvest my grapes and produce quality wines; preserving the taste and precious wine aroma is of utmost importance to me. With ALKOvin™ active liner’s security, I do not have to worry anymore about reductive notes and flavours after bottling; I feel assured that my wine will arrive to the consumer with optimal aroma and taste.”
