Sidel delivers wave-shaped base for rPET bottles
Sidel extends its StarLITE-R range, a dedicated portfolio of bottle bases for recycled PET (rPET), with StarLITE-R Nitro, a distinctive wave bottle base design for nitrogen-dosed still beverages and edible oils.
Sidel delivers StarLITE-R Nitro, a distinctive wave bottle base design for nitrogen-dosed still products.
Nitrogen dosing adds a small quantity of liquid nitrogen to beverage and food products which enables an increase in pressure inside the bottle, aiding the pack’s resistance as it travels through the supply chain.
The design is compatible with any existing bottle shape, from 0.2L to 2.5L. It also features optimized mold base geometry and an efficient venting system, which facilitate blow and shape processes, and help achieve perfect shaping easily.
High mechanical performance
With 100% rPET, StarLITE-R Nitro secures production speeds up to 2,700 b/h/m for single-serve formats or 2,500 b/h/m for multi-serve bottles.
The design has also undergone stringent testing including drop tests with no base breakage. The new Nitro base features an ideal standing surface to secure bottle stability. It can also withstand storage up to 38°C.
The bottle base design draws upon Sidel’s patented mold technology that features 8 to 10 waves to withstand high internal pressure resistance, between 0.5 to 0.8 bar, even with lightweight bottles.
In addition, the bottle base is compatible with Sidel’s range for SBO blowers: series 2, Universal and EvoBLOW and can easily be retrofitted onto existing production lines and molds.
Sustainable packaging with emission reduction
For a 0.5L bottle, by switching from virgin PET to 100% rPET StarLITE-R Nitro base, manufacturers can reduce carbon dioxide tonnage produced by 32%.
With the Nitro base’s optimized venting design, the packaging reduces blowing pressure needed by combining grooves with venting holes to achieve an 18bar blowing pressure for single-serve format, compared to 24bar for market average. This results in a 25% CO2 reduction.
