The screw closure is suitable for plastic containers with a 50 mm neck finish. A slit flex band provides superior tamper evidence and brakes reliably with first opening. The closure is equipped with an EPE/PET liner for safe sealing – the PET side, positioned towards the filled product, provides chemical persistence. The integrated cutter on top of the closure supports easy opening (cutting) of the sealing foil – in case of the IHS version.
