Nitrogen Flush
Nitrogen flushing involves replacing oxygen with nitrogen, an inert gas that does not oxidize food.
Contrary to popular belief, nitrogen does not extend shelf life. Its main purpose is to prevent vacuum pressure from crushing delicate items such as crisps or biscuits.
Nitrogen flushing is available for pillow bags.
The basics
What is Nitrogen Flushing?
Nitrogen flushing (also called Modified Atmosphere Packaging or MAP) is a proven preservation technique that replaces the air inside the packaging with food-grade nitrogen. Nitrogen is an inert gas that displaces oxygen without creating a vacuum.
By removing oxygen and creating a protective cushion of nitrogen, we protect delicate products from being crushed by external pressure during transit and handling.
Your dry goods arrive looking exactly as they did the day we packed them, intact and ready for the shelf.
