Sidel unveils 100% rPET bottle base for still beverages

FRANCE – Sidel has introduced an innovative packaging solution designed to support high-speed production while integrating 100% recycled polyethylene terephthalate (rPET) for still beverages, such as water and juices.

The new bottle base, named StarLITE-R STILL, incorporates patented technology aimed at improving material stretching, distribution, and venting for easier shaping. It also features an efficient cooling circuit tailored for rPET, ensuring optimal performance during production.

The design of the StarLITE-R STILL base reduces blowing pressure by up to 20%, resulting in notable energy savings and reduced production costs, all while maintaining high product quality.

This innovative solution is projected to decrease carbon dioxide equivalent (CO₂e) emissions by approximately 51 tonnes (t), contributing to a smaller environmental footprint for manufacturers.

A key benefit of the StarLITE-R STILL base is its compatibility with existing production lines, making it easy to retrofit.

Sidel emphasizes that the base retains its shape, ensuring it does not deform or break, which guarantees the integrity of the bottle throughout production, storage, and transportation.

The efficient cooling process of the base is particularly advantageous for high-speed production, as rPET materials typically require higher temperatures during processing.

The solution is versatile, designed to accommodate round, square-round, and rectangular-shaped bottles in single or multi-serve sizes, ranging from 250ml to 2.5 litres.

For single-serve production, the base supports rates of up to 2,700 bottles per hour per moud, while multi-serve production can reach up to 2,400 bottles per hour per mould.

Mikael Derrien, Sidel’s Packaging Innovations Manager, highlighted that food and beverage manufacturers are increasingly seeking designs that balance lightweighting, aesthetic appeal, and high-speed production compatibility.

These manufacturers aim to lower production costs through reduced blowing pressures, improved energy efficiency, and a reduced carbon footprint in response to regulatory pressures and consumer demand for more sustainable products.

Earlier this month, Sidel further advanced its efforts in the beverage sector by enhancing CR Beverage’s production capacity in China.

Sidel provided three high-speed aseptic packaging lines to meet growing consumer demand for high-quality, healthier, and environmentally friendly packaged beverages.

The new lines at CR Beverage’s Yixing and Chengdu plants include the Aseptic Combi Predis FMa and Fmac models, tailored for a wide range of beverages, and are capable of producing up to 54,000 bottles per hour for 450ml formats and 27,000 bottles per hour for one-litre bottles.
