High speed PET bottle barrier treatment

Supplier News

WITH output rates rising to 40,000 bottles/hour, the new Actis 48 launched by Sidel is the world's fastest equipment for PET bottle barrier treatment.

Completing the Actis machine range, the new model meets the liquid food market's demands for high speed while guaranteeing top-notch packages at lower costs.

The Actis process consists of depositing a thin layer of hydrogen rich amorphous carbon inside a PET bottle. By reducing CO2 loss and O2 ingress, the Actis process extends the shelf life of sensitive drinks like beer, CSDs, juice or tea packaged in PET bottles up to about 600ml in size (bottle height under neck ring: 254 mm, diameter 75 mm).

The Actis treatment brings also significant savings in materials costs because bottle weights are lighter. For example, a 600ml PET bottle for CSDs, weighing 28g, has a shelf life of about 8 weeks. But that same bottle, when Actis treated and lightened to 23g, has a shelf life of more than 20 weeks, which results in an 18 percent savings in PET resin.

As with the Actis 20, the Actis 48 can handle two types of barrier treatment:

* Actis, with a coating time of 2.5 seconds, a treatment thickness of 0.15µm, and an output rate of 30,000 bottles per hour;

* Actis Lite, with a coating time of 1.2 seconds, a treatment thickness of 0.06µm, and an output rate of 40,000 bottles per hour.

The design of the Actis 48 is based on proven rotary kinematics, and the machine's basic features remain the same: vacuum system, plasma technology, process time and positive transfer.

The Actis process guarantees the same superior performance, increasing bottle barriers to O2 by 30 times and the CO2 barrier by seven times.

Compared to the Actis 20, the new machine offers innovations in mechanics, with higher output rates per station for the same level of performance and even lower operating costs.

The first Actis 48 machine will begin production as part of a complete line delivered by Sidel in the second half of 2006 for the beer market.
