Vacuum Barrier’s NITRODOSE ® Liquid Nitrogen Injection systems provide the most precise liquid nitrogen dosing to add strength to non-carbonated beverages for light-weight packaging and displace oxygen to extend shelf life.
The NITRODOSE ® Liquid Nitrogen Injection systems are designed to inject a drop of rapidly expanding liquid nitrogen into the headspace of a container before capping or sealing. The resulting pressure adds strength to thin walled containers and reduces the headspace oxygen content.
NITRODOSE ® Liquid Nitrogen Injection systems are used for both hot and cold fill light-weight packages with accurate pressure achieved. Various types of NITRODOSE ® Liquid Nitrogen Injection systems are available for different requirements.
