korkkikuoresta

Korkkikuoresta, meaning "cork bark" in Finnish, refers to the outer protective layer of the cork oak tree (Quercus suber). This material is harvested sustainably, as the tree regenerates its bark after removal. Cork is a unique natural product characterized by its light weight, elasticity, impermeability to liquids, and excellent insulating properties. Its cellular structure, composed of small air-filled cavities, contributes significantly to these characteristics.

The primary use of cork bark is in the production of cork stoppers for wine and other beverages. This application leverages cork's ability to create a tight seal, preventing oxidation and preserving the contents. Beyond stoppers, cork is utilized in a wide array of products. These include flooring and wall tiles, which offer sound and thermal insulation, as well as shock absorption. In fashion and accessories, cork is employed for making handbags, wallets, and footwear due to its durability and distinctive aesthetic. Its natural, hypoallergenic, and flame-retardant qualities also make it suitable for use in various industrial applications, such as gaskets, insulation boards, and even in aerospace for heat shielding. The harvesting process involves careful stripping of the bark, typically every nine to twelve years, ensuring the long-term health and survival of the cork oak forest.
