Hot filling processes as commonly used in the JETS (Juices, Energy Drinks, Teas and Syrups) market, are a particular challenge for packages and closures. Being filled at a temperature of +85-88°C, inverted for closure and headspace pasteurization and finally cooled down to < 40°C, the closures need to withstand hydrostatic bottle contraction and guarantee a tight seal during the entire hot filling process.
BERICAP closures for hot filling process stabilize the bottle neck and prevent deformation due to the unique DoubleSeal technology. Thus they ensure a tight seal despite the high temperature treatment. The DoubleSeal system allows thinner neck walls to be used, which lightens the bottle weight and promises convenience for the consumer when opening.
