Krones NitroHotfill hot-fill system
Krones has released an updated version of its NitroHotfill process. This technology enables bottles to be produced with a minimised weight without featuring the typical vacuum panels. The process requires less energy and is more cost-effective overall, the company says.
Filling temperatures of up to 90°C are possible with the system, and the same designs can be handled on both aseptic and hot-fill lines.
The bottle’s base design has also been improved: in addition to the bases currently in use - which permit container weights of just 15.5 grams for 500 mL bottles, for example - flatter, design-optimised bases are available, which can improve the visual appearance of the bottles.
According to the company, the system requires up to 40% less energy than conventional hot-fill processes, offers potential for lightweighting and enhanced scope for creative design, with panel-free sidewalls and flatter bases.
