All the phases in the production process.

All the phases in the production process.

Thanks to the high level of expertise in the processes involved in bottling and the use of plants that are state-of-the-art in terms of technology, Lete, Prata and Sorgesana waters on the consumers’ table are the same as when they bubble out of the spring.

Fase 1: Start Up

The production process start-up takes place in the presses department where the PET (polyethylene terephthalate) granules are dried, brought to a temperature of about
300°C and mixed in the master, which gives them the desired colour. The PET is then injected into multiple moulds that produce thousands of preforms (semi-finished items) per hour, from which the bottles are made by blowing.

Fase 2: The Bottle

The preforms are sent to the blowing machines that heat them in infrared ovens to temperatures of over 100°C and then add them to the moulds. Here the preforms are blown with jets of high pressure air to give them their bottle shape.

Fase 3: Filling the bottles

The bottles are sent to the filling unit consisting of three machines together: the steriliser, the filling machine and the lid assembly machine.

Fase 4: Labelling

In the steriliser, the bottles, even though they are already sterile, are sanitised and rinsed again. The bottles are filled in the filling machine and sent to the lid assembly machine, where the lids are applied, complete with a guarantee seal.

Fase 5: Packaging

The filled bottles with their lids are sent to the labelling machine that wraps them with a label; the labels on the bottles are then marked by laser to indicate the production lot and the expiry date.

Fase 6: Distribution

The packs are sent to the pallet machine that arranges them into carefully organised layers on top of each other with a sheet of card placed in between, before they are then wrapped in film with expandable properties, making the pallet suitably solid and stable for storage and vehicle transportation. Wrapping the pallets in expandable film also protects them from external agents.
