Ventilating aluminium closures (Topvent)
Ventilating aluminium closures are good for fruit juices - also with carbonic acid, hot and cold fillings, heat exchangers and suitable for pasteurisation.
The closures can be delivered with transparent and body colours as well as in lots of printed versions. They are available with a locking ring or with vertical notches and in addition with head vent.
An overpressure generated by fermentation escapes via the bottle mouth when the TOPVENT will be used.
TOPVENT KR (with head cutting)
The closure TOPVENT KR is equipped with an additional security in case that the standard blow-off function e.g. by firm reclosing is no longer given.
TOPVENT for carbonated beverages
This closure is equipped with a higher compressive strength, which guarantees a processing with the same machine settings as the TOPVENT.
