Cork: a noble material for effective preservation

The H22x25/21 mm cork stopper is made from untreated natural cork, a plant-based material renowned for its exceptional preservation performance. Used for centuries, cork remains one of the few materials today that combine durability, effectiveness and respect for the environment. Each stopper comes from the bark of the cork oak, harvested by hand without felling the tree, using responsible and renewable forestry practices.

Its unique cellular structure, made up of millions of microscopic air-filled cells, provides a natural barrier against moisture, oxygen and external contaminants. This configuration makes it a remarkable thermal and chemical insulator, drastically reducing the deterioration of sensitive products. Whether for aromatic liquids, vegetable oils, medicinal powders, teas or artisan preparations, the stopper ensures optimal preservation, with no migration of substances or change in taste.

Cork is also valued for its natural flexibility, which allows it to adapt perfectly to the shape of the neck without cracking or deforming, even when temperature or ambient humidity changes. This adaptability ensures an even, long-lasting seal, without resorting to synthetic materials or complex screw systems.

So this stopper is not just a simple closure: it is a true guarantee of quality and longevity for your products. Combining tradition and innovation, it meets the requirements of professionals while being part of a responsible approach to consumption.

Versatile use across many sectors thanks to this H22x25/21 mm cork stopper

Thanks to its generous size and dense structure, the H22x25/21 mm cork stopper is perfectly suited to a wide range of professional and creative applications. Its 25 mm top diameter, combined with a slightly tapered 21 mm base, allows it to fit a wide variety of glass container necks, whether standard or slightly irregular. This taper ensures a stable, airtight closure, even with dimensional tolerances, which makes it particularly popular in artisan or semi-industrial production lines.

In the drinks sector, this stopper is frequently used for upmarket spirit bottles, artisan liqueurs, infused rums or homemade syrups, where it plays a dual role: preserving the quality of the liquid and enhancing the premium image of the product. Its presence immediately conveys the feel of a noble, carefully crafted, authentic product. It is also very popular with producers of infused oils, flavoured vinegars or other plant-based liquid preparations, as it effectively protects the contents while respecting natural preservation standards.

The herbalism and natural cosmetics sector also finds this stopper well suited to its needs. Thanks to its chemical neutrality, cork releases no compounds likely to alter plant extracts, active powders, macerates or essential oils.
