Crimp closure, N 20, alu., center tear off, no liner

Center tear off caps are crimp caps with tamper evidence. In order to be able to access and penetrate the septum, the middle cover needs to be removed from the center hole. They can be combined with all septas N 20 or stoppers N 20. Nowadays so-called flip top / flip off are mainly used in the packaging sector, which are basically center tear off caps with a tear open aid in the form of a plastic lid.
