Groupe Sidel has introduced Predis, a dry decontamination system for PET preforms, designed for products that need extended shelf life, such as dairy beverages and fruit juices.
The patented Predis uses hydrogen peroxide vapor on Sidel's Combi system, an integrated blowing, filling and capping machine. Calibrated nozzles deposit the heated hydrogen peroxide vapor, which condenses onto the inside walls of the preform. The preforms are heated in an oven — a conditioning process that guarantees activation of the vapor in the preform.
Dry decontamination uses no water and very little chemicals. It consumes very little energy, according to Sidel.
Applications include all types of preforms used in bi-orientation, such as PET, polypropylene and polylactic acid. Outputs range from 10,000-36,000 bottles an hour.
Sidel is based in Le Havre, France. Its U.S. headquarters, Sidel Inc., is in Norcross, Ga.
