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.

At a glance

• Bottling of hot products of up to 90 °C into PET containers
• No more restrictions to the bottle design through panels
• Blowing and filling with outputs of up to 70,000 containers per hour
• Suitable for:
  • Bottle volumes of up to 2.0 litres
  • 38 mm neck finish diameter
  • Standard and lightweight containers

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.
