ACTEGA is the world's leading supplier of sealants for closures and glass containers; in the case of water-based sealing compounds for cans ACTEGA leads the field in technology. These products are used to make seals between the contact surfaces, such as glass on metal (bottle closures) or metal on metal (can ends). They ensure that the contents and other substances such as CO2 remain inside the packaging, and any contaminants remain outside.
