Carbonated Soft Drinks (CSD) & Carbonated Water need special handling. While unavoidable damage to PET bottle necks can occur accidentally, even small scratches on the inside bore seal or dents on the outside surface of the neck are likely to endanger product quality. BERICAP developed the specific DoubleSeal™ technology, which, as the name implies, copes with this minor damage by providing two seals: one on the inner surface and one on the outer. BERICAP closures with the DoubleSeal™ technology can reliably compensate this minor damage. It has been used commercially since 1998 in all climatic zones. Many billions are produced every year in the various BERICAP locations. It is resistant to temperature peaks during transport. Naturally, customized designs are available.
Besides CSD, the DoubleSeal™ technology is applicable to still products with or without nitrogen, hot filled or aseptically filled products, and for all products requiring enhanced sealability of the package.
