The one-piece Double-Seal 38 mm closure. Bericap for the hot fill system leads the industry with the lightest bottles. The technology for the exclusive DoubleSeal ™ 38mm cap. de Bericap is already marketed in the North American market. The design is considered ideal for hot fill applications as it supports, rather than distorts, the finish compared to traditional two-piece closures that cannot support the finish when softened due to hot filling of the product. DoubleSeal ™ caps provide lateral pressure, opposing the force of pressure from both the inside and the outside, which also results in a superior seal compared to the two-piece method.
