The pores of the colmated cork are filled, which significantly improves its properties. This makes the personalisation of the closure more readable and it better preserves the properties of your product.   Colmated cork stoppers are often used with heat shrink capsules, complex capsules and aluminium capsules. Eurocap & Eurocork are experienced manufacturers and distributors of a wide range of closures.
