Three times the safety
Overall treatment with gaseous H2O2 sterilises the complete preform at a single blow: at the inside, at the outside and at the neck finish – with the required sterilisation performance.
Extremely reliable preform interior sterilisation
No machine parts touch the inside of the preform during sterilisation. This ensures that the H2O2 gas reaches and thus sterilises all parts of the interior.
No interior recontamination
The system is used between the heating and the blowing module. Immediately after sterilisation, the preforms are blown to form bottles with filtered air.
The Contipure uses just one single medium for the entire sterilisation process. And since it is used to sterilise the preforms and not the bottles, a substantially smaller surface must be covered. Both of these points drastically reduce energy and media consumption.
Suitable for lightweighting
Sterilising preforms stops them from shrinking. This is not the case when completely blown bottles are sterilised. As a result, preforms can be designed lighter right from the beginning.
Gentle and fast process
The use of a gaseous medium leads to very short process times – without harmful condensation and with minimum residue values.
