This European Standard specifies the dimensions of the 38 mm screw finish with three (3) thread starts for flat waters and non-carbonated beverages. This finish can be used for aseptic filling and filling with introduction of nitrogen (0,7 bar max.). This finish is designed to take a tamper evident plastic closure only. During first opening, the tamper evident band will separate from the closure shell and stay on a one way bottle neck or like bottles in the returnable market, the tamper evident band will tear but will remain connected to the closure shell. This finish is for non crystallized necks only.
