Sidel launches 100% r-PET nitrogen-filled bottle base solution

        Sidel has expanded its r-PET base portfolio, the StarLITE-R series, with the launch of the StarLITE-R-Nitro, a unique wavy base design for nitrogen-filled still beverages and edible oils.

        High mechanical strength

        It is understood that nitrogen-filled beverages and foods often add a small amount of liquid ammonia to increase the pressure inside the bottle to improve the packaging's resistance in the supply chain. The StarLITE-R-Nitro base design draws on Sidel’s patented mould technology, which features 8 to 10 waves to provide high internal pressure resistance of 0.5 to 0.8 bar, even for lightweight bottles. The base has been rigorously tested, including drop tests where the base breaks. The new Nitro base has an ideal upright surface to ensure bottle stability. It can also withstand storage at up to 38°C.

        In addition, the base is compatible with Sidel’s SBO blow moulders Series 2, Universal and EVOBLOW, and can be easily retrofitted to existing lines and moulds.

        Sustainable packaging helps reduce emissions

        StarLITE-R-Nitro uses 100% r-PET, which can ensure the production speed of single-serve packaging up to 2700 b/h/m and the output of multi-serve packaging up to 2500 b/h/m.

        Sidel says that for a 0.5L plastic bottle, manufacturers can reduce carbon emissions by 32% by switching from virgin PET to a 100% r-PET StarLITE-R Nitro base. Thanks to the Nitro-base's optimized ventilation design, the base combines grooves with ventilation holes to reduce the required blowing pressure, achieving a single bottle blowing pressure of 18bar. In comparison, the market average blowing pressure is 24bar, which will reduce carbon emissions by 25%.
