    NitroHotfill process for hot filling of PET containers

      More freedom during hot filling

      Be free!

      Who says hotfill bottles absolutely need compensating panels? We definitely don't! With the NitroHotfill process, just a little bit of nitrogen is added to the bottle after filling. This increases the interior pressure and balances the shrinking behaviour – even when it comes to light-weight containers. A clever design for all who do not want to be restricted in their packaging design any longer.

      Benefits to you

      NitroHotfill is an especially economic and flexible alternative to the conventional hot filling process.

      This process...

      • enables material savings of up to 30 percent.
      • no longer requires the panel design for compensating the vacuum pressure.
      • reduces both, the rinsing air consumption and the rinsing times during the stretching process.
      • enables station outputs of 2,500 containers per hour during stretch blow moulding.
      • reduces the change-over times for moulds via quick-change systems.
      • increases the stability of light-weight PET bottles and the transport properties.
