In 2017, the Sidel Aseptic Combi Predis 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 solution in early 2000, the repeated orders recorded by this technology underline its success.

According to Sidel, since the first FDA approval, many beverage and dairy players, located in the US, Asia, and South America, have trusted the company’s 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 liters of water and 60,000 tons of PET, Sidel said.

The Aseptic Combi Predis differs from former aseptic bottling technologies because the PET package sterilization already occurs at the preform stage rather than during the bottling phase. The solution marks an essential step towards sustainable production because it does not require any water and uses only a minimal amount of chemicals. Its blower oven activates the sterilizing effect of the hydrogen peroxide (H2O2) vapor, thus eliminating the need for additional heating of the preforms, saving further on resources.

Designed to offer maximum safety and simplicity


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, says Sidel. The dry preform sterilization before the oven prevents re-contamination and avoids the need for blow molder sterilization. It also claims to eliminate constraints related to the bottle shape’s complexity. Therefore, the solution can handle bottle formats from 200 ml to 3 liters with any shape. For better flexibility, format changeovers are easy and fast, taking only one minute per mold. In its latest generation – the Versatile Aseptic Combi Predis – the solution claims to manage still beverages and carbonated soft drinks in PET on one piece of equipment.

Role in sensitive beverages and liquid dairy production

Sidel says, players across the globe have taken up the opportunity to acquire the Sidel aseptic blow fill seal system to manufacture and distribute shelf-stable low acid products in PET bottles. These include milk and liquid dairy products, dairy alternatives, and plant-based beverages like soy milk and coconut drinks. On top of being compliant with the FDA’s current Good Manufacturing Practice (cGMP) requirements and bearing the 3-A certification for its sanitary design since 2017, the solution has also been approved by the Canadian Food Inspection Agency (CFIA), a must-have for selling sensitive products in the Canadian market.


“With the world’s first FDA-approved aseptic solution with dry preform sterilization on the market three years ago, Sidel has been enjoying a continuously growing global leadership role in sensitive beverages and liquid dairy production technology. The high level of customer acceptance and the many repeat orders are due to the fact that our patented system is 100% safe and simple for the packaging of low acid sensitive products in PET bottles, sold through ambient chain. We are very proud of this big success,” says Guillaume Rolland, vice president Sensitive Products at Sidel.

“Also, thanks to the great ease of operations offered by the solution, the FDA validation can be applied to upgrade the Aseptic Combi Predis already installed and running in customer plants. This opens the doors to new business opportunities for customers willing to start selling low acid products to the US,” concludes Rolland.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
