Aseptic PET filling: maximum safety and simplicity
Sidel | In 2017, the Sidel Aseptic Combi PredisTM blow fill seal filler was validated by the American Food and Drug Administration (FDA) for low acid products sold in the US – an industry first. With more than 180 references at major beverage and dairy companies since the launch of this safe and simple solution in early 2000, the repeated orders recorded by this technology underline its success.
Since the first FDA approval, many beverage and dairy players, located in the US, Asia and South America, have trusted Sidel’s proven dry preform decontamination technology to develop their business in the US.
This customer success reflects the global achievements collected by Predis technology since its launch: it has decontaminated more than 60 billion bottles, while saving over 10 billion litres of water and 60,000 tons of PET. The Aseptic Combi Predis differs from former aseptic bottling technologies because the PET package sterilisation already takes place at the preform stage rather than during the bottling phase.
The solution marks an important step towards a sustainable production because it does not require any water and uses only a minimal amount of chemicals: its blower oven activates the sterilising effect of the hydrogen peroxide (H2O2) vapour, thus eliminating the need for additional heating of the preforms, saving further on resources.
Dry preform sterilisation
The Sidel Aseptic Combi Predis contributes to production simplicity and reliability, because a line with a small sterile zone and minimum critical factors is managed and maintained more safely, easily and effectively. The dry preform sterilisation before the oven prevents re-contamination and avoids the need for blow moulder sterilisation.
It also eliminates the constraints related to the bottle shape’s complexity. Therefore, the solution is able to handle bottle formats from 200 ml to 3 L with any shape. For greater flexibility, format changeovers are easy and fast, taking only one minute per mould. In its latest generation – the Versatile Aseptic Combi Predis – the solution is even able to manage still beverages and carbonated soft drinks in PET on one piece of equipment.
